Interfacing a linear Stirling cooler to a spaccborne sensor system poses some unique challenges with regard to achieving high thermal efficiency within the mechanical and integration constraints of the cooler and sensor system. Interface component de

In the case of modern infrared focal planes, one of the major problems is related to the noise contribution of the cooled, impedance-matching device used as the preamplifier stage in the detector electronics system. An ideal preamp device should have

Preliminary designs for the NASA/Stanford GP-B Relativity Gryoscope Experiment indicate the desirability of having a capability for assembling and disassembling connections at 4 K which are leak tight to superfluid helium. A series of experiments wer

We introduce a new P-channel, enhancement mode, Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) which is optimized for use at liquid helium temperatures. The new device, now labelled the ZK-111, operates very well to at least 1.8K. It can

We tested two samples of a commercial shielding alloy at 300, 77, 4 and 1.91 Kelvin, using field strengths of 4 and 50 gauss rms and frequencies from 0.08 Hz to 10 KHz. Both samples were effective shields, even at 1.91 Kelvin. One of the samples, whi

It is pointed out that the simple and traditional method of measuring resistance using an electrometer is ineffective since it is limited to a narrow and nonrepresentative range of terminal voltages. The present investigation is concerned with a resi

The Infrared Astronomical Satellite (IRAS) operates in a circular sun-synchronous orbit at 900 km. This orbit carries it through the radiation zones of the South Atlantic Anomaly and the polar regions. Penetrating radiation, mainly protons and electr
