Performance of the pulse-detection algorithm for the PANDA electromagnetic calorimeter

Contact person: Myroslav Kavatsyuk

The PANDA collaboration at the future FAIR facility at Darmstadt, Germany, will employ antiproton annihilations to investigate yet undiscovered charm-mesons, hybrids and glueballs. To discover such states it is important to build detectors with outstanding performances in terms of particle detection and event selection. This requires developing special front-end electronics and new techniques of digital data treatment. Our group is designing digital read-out electronics for the ElectroMagnetic Calorimeter (EMC), one of the crucial sub-detectors of PANDA experiment.

The PANDA EMC aims to register photons in a very broad range of energies, namely between a few MeV and 15 GeV. In order to achieve such a dynamic range, electronics should be able to efficiently detect pulses of very low amplitude and discriminate them from electronic noise. The analogue signals from the EMC preamplifiers are digitized with a sampling frequency of 80 MHz. These data are being processed in real-time by a FPGA, a dedicated programmable chip with implemented pulse-detection algorithms. The efficiency of pulse-detection should be verified under different conditions. The aim of this project is to perform series of measurements with an EMC prototype and evaluate the performance of the algorithm implemented in hardware.
