Superdry

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)
