**Amplifier Testing for Cryogenic SiPMs Detector as part of the ALPHA-3 Upgrade**
Hi, my name is Chalisa Visvajit, a Mechanical Engineering student from Chulalongkorn University, Thailand. I had the opportunity to work with the ALPHA experiment at CERN. My project focused on integrating and testing silicon photomultipliers (SiPMs) under cryogenic conditions for the ALPHA-3 trap. These detectors support non-destructive antihydrogen spectroscopy aiming to achieve the first detection of fluorescence from stable antimatter atoms without annihilation. My role involved amplifier circuit testing, system integration, and cryostat testing to ensure reliable photon detection at temperatures near 4 K in a vacuum chamber..
