Description
The installation of a new lead tungstate calorimeter (ECAL) insert in Hall D’s GlueX detector at Jefferson Lab (JLab) will allow for the improved reconstruction of η/η’ decay channels. The ECAL is necessary for the upcoming Jefferson Lab Eta Factory (JEF) experiment, which aims to study rare decays of eta mesons. The insert consists of 1596 lead tungstate scintillating crystals which have been installed in the center of the detector’s lead glass forward calorimeter (FCAL). My work during the summer of 2024 centered on this hardware upgrade, involving the testing of the light-monitoring system (LMS), ECAL modules, and the installation of cables and readout electronics. The detector will be ready for its first run as a part of the JEF experiment in January of 2025. I will present an overview of this new calorimeter and my contribution to the hardware upgrade in Hall D.
