neuroanatomist, please explain WHY someone would stick liquid helium (liquid nitrogen, liquid oxygen, etc) into a sealed and unvented container? Was there a vent that was clogged, and what could clog it firmly enough that the container blew before the clog blew? I understand that helium is getting harder to obtain, and much more expensive - true?
Liquid helium cooling is the way to go!Liquid cooled cameras. Sealing to keep the liquid *in* instead of out.
Nope, that's a really bad idea. Helium used for liquid cooling does evaporate as gas, and needs to be replenished. Know what happens when you replenish LHE into a sealed container? I can't speak for a camera, but I know what happens when the pressure release valve on an MRI is left closed when the LHE is being refilled. KABOOM. Lots of structural damage. Fortuntely it happened in the middle of the night when no one was around.
