Abstract:

This proposal covers the development of a 0.25 watt, 80 K mechanical cryocooler for
use in sensor cooling in space.  The cryocooler will use the Mikulin pulse tube cycle
that has no moving parts inthe cols section of the cryocooler.  The elimination of
cold moving parts removes the main sources of failure and of vibration inthe cryocooler.
 Lifetimes of over five years should be possible with this cryocooler cycle.
