30 September 2004 Cooling of ground-based telescope instrumentation: the LINC-NIRVANA cryostat
Author Affiliations +
The MPIA in Heidelberg has built many instruments for IR observation over the years. While the previous instruments were moderate in size and could easily be enclosed in a liquid nitrogen dewar, future instruments will require different cooling concepts. The use of Gifford McMahon coolers was chosen for some instruments, but has the disadvantage of low frequency vibrations. The recently-developed pulse tube coolers have lower vibrations but other disadvantages. For the LINC-NIRVANA cryostat, we plan to build a cooling system with a constant flow of Helium through a heat exchanger inside the cryostat. This cooling concept could also be expanded to future instrumentation for the next generation of telescopes.
