A Fiber Detector to Monitor Ortho-Ps Formation and Decay (CERN AEgIS)

Work from my time at the AEgIS experiment at CERN has been published in Nuclear Instruments and Methods in Physics Research Section A. The paper describes a scintillating fiber detector developed to monitor ortho-positronium (o-Ps) formation and decay, used in the context of antihydrogen production experiments.

Summary: We present a scintillating fiber detector designed to track ortho-positronium annihilation photons in the AEgIS apparatus at CERN. The detector provides real-time monitoring of o-Ps formation efficiency, critical for optimizing antihydrogen production rates. I contributed to detector calibration and data analysis during my technical internship at CERN in 2020.
