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 at HI-Mainz is developing the backward end-cap of the electromagnetic calorimeter.
For this prototype, the original design foresees that analogue signals are guided over several meters to the analog-digital converters.
The so-called Hit-Detection ASIC is a multichannel sampling digitizer with additional internal digital signal processing based on an analogue transient recorder with subsequent pipeline ADC.
This setup will eliminate the need for line driver electronics and reduce the amount of signal cables not only for the backward end-cap but especially for the barrel part of the EMC.
In the talk the promising results of the characterization of the Hit-Detection ASIC in its current version will be shown.
