LN2 cryostat warming up

[Olaf Iwert]

Dear Paul,
Dear all,


We at ESO have taken another approach for the VLT instruments based
exactly on the problems you pointed out in your EMail.

Our new Gen.3 cryostat features a hold time between 48 and 54 hours
depending on the orientation.

It is a modular system consisting of a universal cryostat head and
different cooling systems which can easily be attached to it (bath
cryostat in different configurations and a continuous flow system)
