Basic design of the High Precision Thermostat (HPT) of the D1 mission
Abstract
The principal design criteria and main features of the High Precision Thermostat for the D1 mission and the modular, mechanical, and electrical structure of the experiment facility are outlined. The design of the 4 stage scanning ratio calorimeter used for measuring the isochore specific heat capacity of SF6 at its critical point is described. Characteristic performance data as well as the characteristics of the loops for high precision temperature measurement and control (down to less than 1 mK) for the calorimeter's stages are presented.
