Development of a controlled and monitored water cooling system for CBM-MUCH detector

The CBM experiment at FAIR is being designed to explore the QCD phase diagram of high baryon density matter using high-energy fixed target nucleus-nucleus collisions. Muon Chamber (MUCH) is the detector to be used in CBM to detect low momentum muons, originating from the decay of low-mass vector mesons. The final design of the muon detector system consists of 6 hadron absorber layers and 18 Gaseous tracking chambers located in triplets behind each absorber slab. VECC is in process of building and testing the Muon Chambers (MUCH) and related readout electronics for the first two stations. MUCH uses Front End Electronics (FEE) board where the desired operating temperature range is 25-30 °C. Temperature going above this limit will drift the biasing scheme and further increase may lead to damage of FEE boards. We have developed a microcontroller based automated temperature controller system at VECC using multiple temperature sensors (DS18B20) on a One Wire Bus
