Claim 15:
16. An apparatus for transferring heat in 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;
a thermal transfer member mounted to the first end of the horizontal Dewar flask, the thermal transfer member having a first surface and a second surface that is opposite the first surface and that is in direct physical contact with the liquefied gas held in the internal chamber, the second surface having a means for biasing thermal transfer to liquified gas at the bottom of the internal chamber extending in the horizontal direction into the internal chamber and providing 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; and
a means for thermal transfer from the liquefied gas cooled detector to the thermal transfer member.
