Abstract

The measurement and control of the temperature of experimental apparatus in cryogenic environments has been widely explored [1]. Problems in such measurement and control by thermoelectric and thermal resistance effects are receiving constant attention. However, the application of Chromel-P vs. constantan thermocouples to cryogenic temperature measurement and control has not become widespread. The reason for this limited usage is not clear, especially since the sensitivity and potential [1, 2, 3] for this thermocouple system are higher than for the more popular copper vs. constantan thermocouple system. Furthermore, the use of low-thermal-conductivity Chromel-P [3] wire, instead of copper wire, would reduce heat leaks into cryogenic systems.
