A flexible COME and KISS QDC and TDC read-out scheme for PMT, MAPD and diamond detector applications

A flexible COME and KISS Charge-to-Digital-Converter (QDC) and Time-to-Digital-Converter (TDC) read-out scheme will be presented which can be used in a wide range of read-out applications in high energy physics experiments. The focus is on a calorimeter detector read-out via photomultiplier tubes (PMTs) or via multi-pixel avalanche photo-diodes (MAPDs), as well as on diamond detectors for the HADES and CBM experiments at the future FAIR facility in Darmstadt. The detector input signals are integrated with the help of simple analogue electronics (KISS: Keep it Small and Simple). Afterwards the charge measurement is transformed into a Time-over-Threshold (ToT) measurement using an commercial (COME: Use Commercial Elements) FPGA as a discriminator. The well-established TRBv3 platform will provide a precise FPGA TDC for a ToT measurement of the discriminated signals. An 8-channel prototype board PaDiWa-AMPS was manufactured and successfully tested in the laboratory and under beam conditions. In this contribution the current status of the read-out concept is shown.
