Temperature Control Board Design and Validation for Skipper-CCD Sensors Using a Buck Converter

This paper presents the design and validation of a custom temperature control board tailored for Skipper-CCD sensors that are adaptable to diverse experimental configurations. The board features two galvanically isolated sections: a control section incorporating a Raspberry Pi and essential instrumentation components for measurements and board protections and a power section housing the buck converter with corresponding instrumentation components for enhanced protections and measurements. The seamless integration of these sections ensures robust temperature regulation while providing comprehensive safeguards against potential anomalies. Through meticulous design and rigorous experimental validation, the proposed temperature control board offers reliable and precise thermal management tailored to the specific requirements of Skipper-CCD sensors. Illustrated by its application in the OSCURA experiment, this board is a case example, demonstrating its potential extension to other applications.
