About this technology
Overview
NASA Kennedy Space Center seeks partners interested in the Cryostat-100, an absolute heat measurement device for precise thermal performance measurements under actual-use cryogenic-vacuum conditions. It is a liquid nitrogen boiloff calorimeter with upper and lower guard chambers and full vacuum pressure range capability. The Cryostat-100 vacuum cylinder and cold-mass assemblies include handling and manipulation devices to make sample material change-out fast, reliable, and safe for the operator. The boiloff flow from the test chamber is in direct proportion to the total heat transfer rate through the thickness of the test article. Flow rate is typically averaged over the liquid level from 88 to 92 percent to calculate the k-value.
