| The
gas supply to the cryostat is normally commercial, high-purity,
extra-dry, water-pumped nitrogen, MIL-N-6011, Grade A. Other
gases such as Argon (87K), Freon 14 (145K) or Freon 13 (192K) may
be used without modification to the cryostat; for maximum efficiency,
however, custom modifications to our standard cryostat are required
when using coolants other than nitrogen gas |
|
Successful operation with
detector/dewar package heat loads of 2 watts or less may be expected
when Nitrogen gas is used. Capacities to 5 watts and more are possible
with the other gases and custom cryostats. |

The fixed orifice
cryostat will operate successfully over a wide range of ambient temperatures;
-55° to 70° C is usual. |
