Classification: CPC F | IPC F

Claim 0:
1. An apparatus for transferring heat from a liquefied gas cooled detector, comprising:
a horizontal Dewar flask positioned with a length extending in a horizontal direction, the horizontal Dewar flask having an internal chamber for holding liquefied gas, the internal chamber having a first end and a second end and having a top and a bottom; and
a thermal transfer member mounted to the first end of the horizontal Dewar flask, the thermal transfer member having a thermal transfer surface and a second surface that is opposite the thermal transfer surface and that is in direct physical contact with the liquefied gas held in the internal chamber, the second surface has at least one projection that extends in the horizontal direction into the internal chamber of the horizontal Dewar flask and provides a larger surface area in direct physical contact with the liquefied gas at the bottom of the internal chamber than at the top of the internal chamber;
wherein the thermal transfer surface of the thermal transfer member is configured to have the liquefied gas cooled detector mounted thereon.
