ShareMETHOD FOR MEASURING A VACUUM IN AN ENVIRONMENT AT LIQUID HELIUM TEMPERATURES.
Author(s) : CESNAK L., SCHMIDT C.
Type of article: Article
Summary
THE METHOD USES A THIN SUPERCONDUCTING WIRE SUSPENDED IN THE VACUUM VESSEL, THE WIRE IS HEATED BY A CURRENT PULSE. THE COOL DOWN TIME, WHICH DEPENDS ON THE HEAT TRANSFER INTO THE REST GAS AND ON THE AXIAL HEAT CONDUCTANCE OF THE WIRE, IS A MEASURE OF THE VACUUM AND IT IS DETECTED BY THE RECOVERY OF THE WIRE TO SUPERCONDUCTIVITY.
