0 related to the scientific study of very low temperatures and how to produce them --
The cryogenic targets for these experiments are polystyrene shells of 0.7- to 1-mm diameter and 8- to 15-mm wall thickness.
A cryogenic fluidized bed is being evaluated experimentally for the capability to provide this temperature environment.
Of importance in this joint are its strength, leak integrity, and resistance to cooling to cryogenic temperature.
A full density gas tight permeation seal was successfully deposited for retention of the fill gas at room temperature or the ice at cryogenic temperatures.
The cryogenic target can tolerate the asymmetry of a thermal flux as 4th harmonic less than 1%.
They can be applied either at cryogenic or physiological temperatures and down to amounts of a few nanomoles.
Therefore, the layering module design is constrained by the fact that a cer tain par t of the layering channel must be cryogenic.
Volumes of air from the upper stratosphere collected via balloon-carried cryogenic equipment have been found to trap interplanetary microparticles (1).
