Latest Progress Concerning the Front-End Electronics Prototype for the PANDA Barrel EMC — •Aniko Tim Fenske, Kai-Thomas Brinkmann, Hans-Georg Zaunick, and Karl Simon Habermehl for the PANDA collaboration — 2nd Physics Institute, Justus Liebig University, Giessen, Germany
The barrel section of the PANDA electromagnetic calorimeter (EMC) at the future FAIR facility is designed to precisely measure photon and charged particle energies over a wide dynamic range. Achieving the targeted performance requires not only a carefully engineered detector system but also a detailed understanding of its operational behavior under realistic conditions.
Therefore, recent efforts have concentrated on an in-depth analysis of calibration data and functional tests of the readout and front-end electronics. Building on results from the current prototype setup, a comprehensive evaluation of in-beam measurements and laboratory studies has been carried out, with particular attention to the stability, linearity, and noise characteristics of the system. This contribution summarizes the latest findings of these analyses and discusses their implications for the final configuration of the Barrel EMC.
Supported by the BMFTR, GSI and HFHF.
