[ RadSafe ] Electric detector cooling

[Edmond Baratta]

The electric coolers are best where the LN2 supply is not available locally. 
Also, if one wishes to maintain the cooling on the detectors at a remote or 
emergency post, they are valuable.  One drawback is that the resolution is 
not as good.

LN2 seems to be on the decline when it comes to Germanium detector cooling. 
Electric coolers are entering labs here and there. Even though they will 
probably never be as good as LN2 at cooling, they have their advantages. 
What I wonder is if there are any experiences on here of the performance of 
the major models. Primarily I think of:

Canberra Cryo-Cycle
Canberra Cryo-Pulse 5
Ortec X-cooler II

I think the Cryo-Cycle seems very interesting but I haven't had the 
opportunity to try it out. Microphonics and noise (sound) may be the 
drawbacks for that one.

All the best,
