Thermostatting of the RED-100 liquid-xenon emission detector

摘要

The thermal stabilization system of the RED-100 liquid-xenon two-phase emission detector for the experiment aimed at detecting the effect of coherent neutrino scattering off xenon nuclei has been tested. The system is based on thermosyphons (closed two-phase heat pipes) that are filled with nitrogen and use liquid nitrogen boiling at atmospheric pressure as a cooler. The system is capable of keeping the working medium of the RED-100 detector at a temperature of 167 K with a precision of < 1 K.
