Force Intensifier for Low Temperature Use

Abstract

A hydraulic type of force intensifier which uses a solidified gas as the working medium has been developed for use at very low temperatures. It has been used to load an anvil type of high pressure cell with continuously variable pressures in the range up to 55 kbar at 77.4°K with minimal refrigerant consumption. The design and operating characteristics are discussed and suggestions for further utilization of this concept are presented. In its present form the system is potentially capable of generating pressures up to 100 kbar at 4.2°K with a liquid helium consumption of about 1 liter/h.
