X-Message-Number: 22620 From: Date: Wed, 1 Oct 2003 12:44:37 EDT Subject: High temperature cryostat (call to desing) Hi, Some months from now, I may have the possibility to build and operate a cryostat. There are two possibilities: Buy a used dewar and work with LN2. Build a new system working at higher temperature, for example with liquid freon. I know there have been some talks about building such a system. Some concepts have been published, but I have not at hand the drawings of a system ready to be built. If there is on Cryonet some person interested to submit such a concept, pleas let me know. One idea: The system could use both, an electric cooling circuit and a thermal buffer in the form of an LN2 tank. The electric system could bring down temperature from the room one to the dry ice domain and cold GN2 could then liquefy the freon... Any idea, comments suggestions? Yvan Bozzonetti.
