Feature extraction of the electromagnetic calorimeter preamplifier (APFEL - ASIC) for the PANDA experiment at FAIR — Samer Ahmed^1,2, Luigi Capozza¹, Alaa Dbeyssi¹, Phillip Grasemann^1,2, Frank Maas^1,2,3, •Oliver Noll^1,2, David Rodriguez Pineiro¹, Sahra Wolff^1,2, Manuel Zambrana^1,2 und Iris Zimmermann^1,2 für die PANDA Kollaboration — ¹Helmholtz-Institut Mainz, Mainz, Germany — ²Institute of Nuclear Physics, Mainz, Germany — ³PRISMA Cluster of Excellence, Mainz, Germany

The PANDA experiment at the upcoming FAIR accelerator facility will study antiproton annihilation reactions at antiproton beam momenta from 1.5 GeV/c up to 15 GeV/c. With its modular multi purpose detector system it will be able to observe a variety of physics channels. The electromagnetic process group (EMP) at HI-Mainz is developing the backward end-cap of the electromagnetic calorimeter. Within this activity a method for the real time extraction of specific signal features using the APFEL ASIC preamplifier will be developed for the whole PANDA calorimeter. It has to recognise the signal pulse shape whilst ensuring at the same time a single channel threshold for deposited energy of lower than 3 MeV for meet the PANDA requirements. The extraction procedure need to be optimised in terms of resource usage in view of the many read out channels. The talk will discuss the feature extraction with emphasis for its efficient implementation on a FPGA via distributed arithmetics.
