Electron-Beam-Induced Nanowire Assemblies,heir comparison. This paper aims to evaluate the thermal performance data so that cooler-to-cooler comparisons can be made. As part of these comparisons, the paper explores the measured sensitivity of thermal performance to a wide range of operational variables. These include piston and displacer st

Improved Standard Spacecraft Cryocooler Life Test for Space-Based Infrared Surveillancend has accumulated 9 months of operating time as of April 1994. It is currently operating within its required performance envelope of 832 mW at 60K for less than 60 W of total motor power..The ISSC is attractive for near term surveillance applications because of its high cooling capacity at 60K.

All these options have been built into the 80-K controller.

Adaptation of Tactical Cryocoolers for Short Duration Space-Flight Missions at the fundamental and harmonic frequencies through 1000 Hz. NASA/GSFC personnel designed and implemented a low cost active counterbalance to mount on each expander to reduce vibrations. NASA/GSFC’s vibration control algorithm was then used to further null vibrations to below 0.1 Newtons..Character
