Controlling Temperature Regimes of Electronics of the ROC Chamber of the TPC Detector for the MPD Experiment: Comparison of Experimental and Calculated Results

Presented below are the results of the measurements of temperature of simulators of front-end electronic boards (62 pcs), heat sinks for electronic units, housing of the ROC chamber, and the pad plane of the TPC detector for the MPD facility to be operated at the NICA collider. The measurements were conducted for two coolant temperatures. Data of computer simulations, which are in good agreement with the measurements, are also presented. The results reported will be used to develop and optimize cooling and thermal stabilization systems for ROC chambers and front-end electronics.
