Radiation hard environmental monitoring sensors inside the PANDA calorimeter — •Yannik Bettner, Kai-Thomas Brinkmann, Christopher Hahn, Markus Moritz, and Hans-Georg Zaunick for the PANDA collaboration — Justus-Liebig Universität Gießen, 2.Physikalisches Institut
The future PANDA experiment at FAIR will investigate quantum chromodynamics with unprecedented precision. Its target calorimeter is composed of lead tungstate crystals operating at -25∘C. Therefore, an important aspect is the monitoring of temperature, relative humidity and pressure by suitable sensors, in particular close to the front-end electronic to avoid water or even ice formation. The BME280 and the SHT21 sensors were investigated through measurements assessing their performance in the planned setup. Accuracies with respect to the above observables and radiation resistance will be presented. This work was supported by BMBF and HIC for FAIR.
