Re: [APML] Another nail in the coffin

Ahh, superconducting! So instead of hauling up a bottle of nitrogen gas
for purging, you will be hauling along large thermos flask of liquid
nitrogen for a total loss cooling system. Wonder what the ~40 degree
kelvin camera will do to the thermal state of the scope?
Sounds like real fun, even more so if the DEA guys happen to be flying
around with the FLIR system up and running...
