Using the Crystal Barrel-DAQ for the Test-Beamtimes of the PANDA Forward Endcap @COSY — •Benedikt Otto for the PANDA collaboration — Helmholtz-Institut für Strahlen- und Kernphysik, Universität Bonn

In August and September 2023 two test-beamtimes for the partly equipped PANDA forward endcap EMC took place at COSY. For these a data acquisition originally developed for the Crystal Barrel/TAPS experiment at ELSA was deployed.

The PANDA Sampling Analog to Digital Converters (SADCs) were used in self-triggered mode. This comes with the challenge to avoid incomplete events which can be caused by the significant deadtime due to the full waveform readout. To assure a synchronous readout of the SADCs, a custom LVDS-based synchronization bus was implemented.

An adapted version of the CB-SADC firmware with support for the synchronization bus was developed. To handle the data, commercial computing and network infrastructure was used. A total of over 200TB of waveforms were collected and are now being analyzed.

Supported by BMBF and within the programme "Netzwerke 2021", an initiative of the Ministry of Culture and Science of the State of Northrhine Westphalia (project "NRW-FAIR", ID: NW21-024-C).
