In this chapter, we bridge our discussions of the gas and the liquid by considering several aspects of the vapor pressures, P sat, of the two helium isotopes. The P sat vs. T relations for He3 and He4 relative to some fixed absolute temperatures establish convenient and practical temperature...
A large-scale liquid helium (LHe) to high-pressure (HP) gas conversion system has been implemented at the John F. Kennedy Space Center (KSC). Helium is used by the Space Shuttle, Titan, Atlas, and Delta programs for prelaunch processing, during launch count-down, and for postlaunch ...
There are a number of possibilities: construction of a wind tunnel using critical helium gas, free surface testing, low speed flow facilities using helium I and helium ll. At the time of the conference, most consideration had been given to the last possibility because it seemed both possible ...
PURPOSE:To prevent the entrainment of liquefied helium on the suction side of a pressure-reducing pump, by a method wherein for vaporized helium gas, a baffle plate is provided at the outlet of a liquid helium reserver. CONSTITUTION:Herium gas in low temperature and high pressure, which is...

Liquid/Gas Phase Separators for the Superfluid Helium On-Orbit Transfer (SHOOT) Project Three different types of liquid/vapor phase separator were used on the Superfluid Helium On-Orbit Transfer (SHOOT) project, a shuttle attached payload designed to demonstrate the technology required to resupply li...
The theory of the degeneration phenomena of an ideal Bose-Einstein gas is modified so as to make it more in accordance with the thermal phenomena of liquid helium II. At the lowest temperatures the specific heat can be brought in agreement with the experimental data when the plausible assumption...

In order to do this the ASTM standard electrode and the point-plane electrode systems were employed. Although the main emphasis was directed toward measurements on liquid helium, in certain cases liquid nitrogen and cold helium gas were also studied. It was found that the deterioration in ...
