โœฆ Synopsis

The designed, manufactured and certiยฎed devices and metrological systems to control the thermodynamic state of two-and single-phase cryogens are presented. These systems and the developed methodology provide an accuracy of calibration not more than 5 mK for resistive temperature sensors in the range from 1.5 to 300 K and 1.5% or less for radio frequency void fraction sensors intended for helium, hydrogen, nitrogen and others. The thermodynamic diagram temperatureยฑdielectric permittivity for helium is presented as well.

The cooling system of the proposed TESLA 500 superconducting linac makes extensive use of He II two-phase flow. However, there remain a number of open questions about the expected performance of this unique two-phase flow system. One of the purposes of the TESLA Test Facility (lTF) currently under c
