Case appears to be copper lined lead

Case is mostly soldered together

Connectors are likely most properly removed by having a tool that unscrew the aluminum spacers. However, I removed them by cutting into the case and peeling away the threading (lead, so its easy to do). I had to cut some wires to internal electronics for them to release

Some quick tests indicated my unit did not have PCBs, but I'm not confident on that result

==Superdry==
[[File:Oxford superdry advert.png|none|thumb]]
https://academic.oup.com/mt/article-pdf/2/4/b1/48501984/mt00b1.pdf

"The early version of the superdry had an external helium compressor that the head hooked up to. I think this version just uses a stack of TECs, that’s why there is a water connection"

"So you are still stuck with the same issue as other SiLi systems. If they are not kept cold the lithium migrates through the Silicon and it becomes unhappy. I think this would be a better option: "Thermo Scientific Ultra Dry X-ray SDD Silicon Drift Detector Noran System 7"

"Yeah, it seems virtually everything puts out the same preamp ramp. I think some SDD are reversed from SiLi detectors from what i was reading but it still works.

The iXRF MCA I have for my SDD has bias and preamp power outputs to run a SiLi detector too.

And all the configurations in software."

"I am not too familiar with those devices, one potential thing to look for is the sterling cryocoolers have a finite life and slowly loose cooling power over time (and no hobbyist I know of has successfully rebuilt one), so if it is a cryocooler based one that has been left on for 10 years it may be shot. TEC shouldn't have that issue"

"SiLi doesn't suffer from that very much, it can be fine if it's kept warm It's GeLi that dies within hours of warming up(at all)"

Basically looks like this is a stirling cooler that generates the cooling in the unit itself. Otherwise its still a SiLi detector with all of the problems that goes with that (ex: extreme thermal cycling may break it, not ideal to leave at room temp, etc)

I've heard these all went bad (FIXME: add details why)

Detector

2025-04-22T02:32:20Z

Mcmaster:

Some quick recommendations / popular equipment:

*Geiger counter
**GQ
***Ex: GQ GMC-300S
***I'm not as familiar with these but price start quite low
***2025-04-18: $62, [https://www.amazon.com/GQ-GMC-300S-Radiation-Detector-Dosimeter/dp/B0B541D433/ link]
**MightyOhm w/ SBM-20
***Entry level open source kit
***2025-04-18: $120 on Amazon including SBM-20, [https://www.amazon.com/MightyOhm-Geiger-Counter-Kit-Bundle/dp/B08L8FM1H6 link]
**Honorable mention: Civil Defense Geiger counters
***There are a lot of these. But generally best to transfer the detector to more modern electronics (ex: MightyOhm)
*Gamma spectrometer
**Radiacode 102
***Very popular portable / compact gamma spectrometer
***2025-03-18: $250 on amazon, [https://www.amazon.com/stores/Radiacode/page/28ECBF84-111B-4391-9ADB-3C8091AE914F link]
**Ludlum Model 3 Geiger counter
***The US nuclear industry standard Geiger counter / survey meter
***2025: About $400 used on eBay (say wand or LND 723 tube)
**Gamma Spectacular
***If you want to interface to a more specialized gamma spectrometer detector
**Honorable mention: ICX Identifinder
***A community of us exists. In theory better / more industrial than Radioacode + some have neutron detector
***Surplus units generally require some work to retrofit
*x-ray machine / panel
**See [[X-Ray]]

*Neutron detector
**TLDR: no great standard options. Specialized equipment
**Some Russian He-3 tubes work ok
**McMaster: I have a Ludlum Model 15 + some Eberline "sea mines"
**They also tend to be difficult to test without specialized equipment / sources (working fusor, Po, etc)

==DIY x-ray setups==

Ben K x-ray, CBCT "chicken" setup

*originally unshielded but I think is now?
*In CBCT mode runs automatically via arduino and thus person doesn't have to get exposed

Russian fellow: http://habrahabr.ru/post/254015/

*...who gave himself acute radiation sickness. A stern warning to those not taking such a setup seriously

John M dental x-ray setup

*which has about 100 lbs of lead shielding
*also operated remotely via ssh to laptop

==mcmaster rotary stage replacement==

Goal: stop using my Sherline rotary stage and instead use spare CNC rotary stage (from laser machine purchase lot)

Motor: Vexta PH566-B 5 phase stepper

Controller: Rorze RD-053MS

*[[http_//www.wellforces.cn/rorze_data/rd-053ms/rd-053ms_e.pdf|Datasheet]]
*[http://www.rorze.com/english/Tech/controll/RD053MS.pdf Spec sheet]
*Has a lot of pins labeled
*Enclosed in box with cable running to the rotary table
*3 per box
*Need to interface to output Centronix connector

The left side connections are pretty obvious:

*power
*18V to 40VDC
*motor phases

Left side less so

*diff1
*diff2
*4P IN
*FREE
*PHASE OUT
*ALARM OUT

Summary

*Up to 400 microsteps/step
*Current driven...looks like approx. 3.8mA at 5VDC?
*3.3V compatible?

Two ways that step/direction can be configured

Two Clock Input (2CK) (Inputs two clock pulses - CW clock pulse and CCW clock pulse)

*CW+/-: Motor rotates in CW direction with a pulse current of 8 to 20mA from CW+ to CW- terminal.
*CCW+/-: Motor rotates in CCW direction with a pulse current of 8 to 20mA from CCW+ to CCW- terminal.

One Clock Input (1CK) (Inputs clock pulse and direction (CW, CCW))

*CLK+/-: Motor rotates in CW direction with a pulse current of 8 to 20mA from CLK+ to CLK- terminal and UD input off.
*UD+/-: Motor rotates in CCW direction with a pulse current of 8 to 20mA from CLK+ to CLK- terminal and UD input turned ON.

Basically it looks like second is standard step/direction configuration

*Yep buried in later documentation: Selects clock input, Two clock input method (2CK) or Pulse & Direction input method (1CK).

6-2 Full Step Input (4P IN +/-): Motor rotates in full step mode with a pulse current of 2 to 10mA (approx. 3.8mA at 5VDC) from “4P IN +” to “4P IN –”

6-3 Free Input (FREE +/-): The excitation current of motor will become 0 and a motor can be rotated by hand with a pulse
current of 2 to 10mA (approx. 3.8mA at 5VDC) from “FREE+” to “FREE-”.

*NOTE: Do not turn this input ON when motor is running at high speed, this operation would

damage the amplifier circuits.

6-4 Phase Output (PHASE OUT+/-): PHASE OUT output (open collector output) is turned ON at the phase home. One pulse is put out every time the motor moves 7.2゚ in case of 0.72゚ motor. The Duty of output ON is 10%.

6-5 Alarm Output (ALARM OUT+/-): Overheating protection circuit intervenes turning ALARM output ON. (Open collector output ON)

All channels as given are configured the same

*8-1 current range: 1.5A
*8-2 clock select: 1 clock
*8-3 auto current down: on
*8-4:8-8: microstepping: 32
*D1: 0
*D2: 1
*D3: 0
*D4: 0
*D5: 1
*1: to the left, 0: to the right (assuming OFF => 0)

Agilent PS test on CLK input while off (assuming its just a PD)

*0V 3 mA (subtracted from all other values)
*3.3V: 7 mA
*Just under recommended 8mA...maybe I can get away with it for now but long term need to boost it
*8 mA: 3.5 V
*5V: 13 mA
*They said 3.8 mA...are inputs non-uniform?
*20 mA: 6.8 V

(note to self: script a curve tracer...)

BBB test:

*red: STEP+ to P8.13
*black: STEP- to P8.1
*white: DIR+ to P8.12
*blue: DIR- to P8.2

no response

try agilent supply tragging step input

*3.2V: no step
*3.3V: step

Its just too close on the edge for it to work I guess

*This does verify I'm on the right channel

==mcmaster rotary stage replacement==

Goal: stop using my Sherline rotary stage and instead use spare CNC rotary stage (from laser machine purchase lot)

Motor: Vexta PH566-B 5 phase stepper

Controller: Rorze RD-053MS

*[[http_//www.wellforces.cn/rorze_data/rd-053ms/rd-053ms_e.pdf|Datasheet]]
*[http://www.rorze.com/english/Tech/controll/RD053MS.pdf Spec sheet]
*Has a lot of pins labeled
*Enclosed in box with cable running to the rotary table
*3 per box
*Need to interface to output Centronix connector

The left side connections are pretty obvious:

*power
*18V to 40VDC
*motor phases

Left side less so

*diff1
*diff2
*4P IN
*FREE
*PHASE OUT
*ALARM OUT

Summary

*Up to 400 microsteps/step
*Current driven...looks like approx. 3.8mA at 5VDC?
*3.3V compatible?

Two ways that step/direction can be configured

Two Clock Input (2CK) (Inputs two clock pulses - CW clock pulse and CCW clock pulse)

*CW+/-: Motor rotates in CW direction with a pulse current of 8 to 20mA from CW+ to CW- terminal.
*CCW+/-: Motor rotates in CCW direction with a pulse current of 8 to 20mA from CCW+ to CCW- terminal.

One Clock Input (1CK) (Inputs clock pulse and direction (CW, CCW))

*CLK+/-: Motor rotates in CW direction with a pulse current of 8 to 20mA from CLK+ to CLK- terminal and UD input off.
*UD+/-: Motor rotates in CCW direction with a pulse current of 8 to 20mA from CLK+ to CLK- terminal and UD input turned ON.

Basically it looks like second is standard step/direction configuration

*Yep buried in later documentation: Selects clock input, Two clock input method (2CK) or Pulse & Direction input method (1CK).

6-2 Full Step Input (4P IN +/-): Motor rotates in full step mode with a pulse current of 2 to 10mA (approx. 3.8mA at 5VDC) from “4P IN +” to “4P IN –”

6-3 Free Input (FREE +/-): The excitation current of motor will become 0 and a motor can be rotated by hand with a pulse
current of 2 to 10mA (approx. 3.8mA at 5VDC) from “FREE+” to “FREE-”.

*NOTE: Do not turn this input ON when motor is running at high speed, this operation would

damage the amplifier circuits.

6-4 Phase Output (PHASE OUT+/-): PHASE OUT output (open collector output) is turned ON at the phase home. One pulse is put out every time the motor moves 7.2゚ in case of 0.72゚ motor. The Duty of output ON is 10%.

6-5 Alarm Output (ALARM OUT+/-): Overheating protection circuit intervenes turning ALARM output ON. (Open collector output ON)

All channels as given are configured the same

*8-1 current range: 1.5A
*8-2 clock select: 1 clock
*8-3 auto current down: on
*8-4:8-8: microstepping: 32
*D1: 0
*D2: 1
*D3: 0
*D4: 0
*D5: 1
*1: to the left, 0: to the right (assuming OFF => 0)

Agilent PS test on CLK input while off (assuming its just a PD)

*0V 3 mA (subtracted from all other values)
*3.3V: 7 mA
*Just under recommended 8mA...maybe I can get away with it for now but long term need to boost it
*8 mA: 3.5 V
*5V: 13 mA
*They said 3.8 mA...are inputs non-uniform?
*20 mA: 6.8 V

(note to self: script a curve tracer...)

BBB test:

*red: STEP+ to P8.13
*black: STEP- to P8.1
*white: DIR+ to P8.12
*blue: DIR- to P8.2

no response

try agilent supply tragging step input

*3.2V: no step
*3.3V: step

Its just too close on the edge for it to work I guess

*This does verify I'm on the right channel

==Superdry==
[[File:Oxford superdry advert.png|none|thumb]]
https://academic.oup.com/mt/article-pdf/2/4/b1/48501984/mt00b1.pdf

"The early version of the superdry had an external helium compressor that the head hooked up to. I think this version just uses a stack of TECs, that’s why there is a water connection"

"So you are still stuck with the same issue as other SiLi systems. If they are not kept cold the lithium migrates through the Silicon and it becomes unhappy. I think this would be a better option: "Thermo Scientific Ultra Dry X-ray SDD Silicon Drift Detector Noran System 7"

"Yeah, it seems virtually everything puts out the same preamp ramp. I think some SDD are reversed from SiLi detectors from what i was reading but it still works.

The iXRF MCA I have for my SDD has bias and preamp power outputs to run a SiLi detector too.

And all the configurations in software."

"I am not too familiar with those devices, one potential thing to look for is the sterling cryocoolers have a finite life and slowly loose cooling power over time (and no hobbyist I know of has successfully rebuilt one), so if it is a cryocooler based one that has been left on for 10 years it may be shot. TEC shouldn't have that issue"

"SiLi doesn't suffer from that very much, it can be fine if it's kept warm It's GeLi that dies within hours of warming up(at all)"

Basically looks like this is a stirling cooler that generates the cooling in the unit itself. Otherwise its still a SiLi detector with all of the problems that goes with that (ex: extreme thermal cycling may break it, not ideal to leave at room temp, etc)

I've heard these all went bad (FIXME: add details why)

[[File:Identifinders.jpg|none|thumb]]

Originally made by ICX Radiation which was then acquired by Thermo Scientific

"FWIW my source is labeled 1uCi and dated to Jul 2006 (also from Spectrum Techniques)

it reads ~3uSv/h on my spectrometer, which some napkin math tells me it should be ~0.1uCi

though the decay calculator says it should be 0.65uCi

In the non-Ultra models a built-in Cs-137 reference source (<15 nCi/500 Bq) is used for online stabilization and in-situ calibration without user interaction.

this is interesting. I assume your unit does not have an internal source"

"figured a bit more out with the my identifinder, it is complaining about the backup battery being dead (seems to be a smaller battery soldered in the unit) and is loosing its calibration on each bootup. From what I have been able to gather, the cs-137 calibration is mandatory at first boot but them it switches over to the blue led calibration on subsequent power cycles. That probably explains the smaller check source: on the standard it runs a 30s calibration with the 15nCi source at each boot, whereas in the ultra is runs a 180s calibration on the 3nCi once to calibrate the blue LED and then does a blue LED calibration (every 5s apparently)

there is also some sort of background subtraction that it does with the check source, the cs-137 spectrum peak doesn't show up in the downloaded spectrum. If you put an additional source you can still get counts there so its isn't just completely blanking out the area. not quite sure how it works, must just selectively delete some counts"

Blue cap bs red cap?

==Battery pack==
"I did end up ordering a main battery for mine, they are still available from FLIR in both nicad and removable battery (takes 4x AA) version. Almost would have been cheaper to buy another burner unit, it was almost $250 with tax and shipping"

 

== Backup battery ==
hmm so there is good news and bad news, the good news is the battery is a pretty lithium primary cell i a 'cr-1/3n' package from FDK. The bad news is that there aren't any available from the usual digikey etc with tabs

found what appears to be a pretty much oem replacement here <nowiki>https://www.battery2batteries.com/fdk-cr1-3n-pc3-battery-3-pin/</nowiki>

I am kinda 50/50 split on ordering from him, shipping is another $15 so it ends up a pretty pricey battery

probably just going to install a normal cr2032 I have on hand
 
==Cal source==
[[File:Identifier peter cal.jpg|none|thumb]]
Peter unit: 3 nCi (hand written, 15 nCi crossed out)

McMaster order 2024-08

*15 nCi seems to be the standard source
*50 nCi are the lowest COTS source ([https://www.spectrumtechniques.com/product/beta-gamma-laminate-disk-sources/ link])
*However they are made to order, so you can get a smaller one if needed. In theory down to about 3 nCi. Contact them for details

 

==Serial port==
messing around a bit with the software, it is pretty basic but mostly functions. basically, from what I have been able to gather it doesn't actually control the unit in any way but it lets you pull the data off. Seems to be working to manually set up an acquisition and then clicking the 'load actual spectrum' button which grabs the current counts and displays it (it adds to the currently displayed spectrum). The software itself has that early 2000s clucky vibe (not unlike the skyscan...) but was able to make a plot

when the software starts up it sends 'serial' and gets a text response with the serial number

I haven't tried sniffing in operation, but despite what the manual suggests none of the buttons do anything except the 'grab spectrum'

so far the process has all been pretty clunky, you first need to create a text file in the install folder with some magic incantations from the manual. Furthermore, the manual says the unit should be at 9600 baud but mine is at 38.4k (even after factory reset) so that took a bit of guess work

oh also, don't be fooled by the usb-shaped port. It is actually RS232

also some weird behavior that confused me, it seems like the max232 chip is powered by the data lines (?!) internal to the unit. I didn't see normal rs232 voltages until I hooked up the rx pin, then the tx pin started working. Very weird
