New Electronics for the HADES Drift Chambers — •Jan Michel1, Ole Artz1, Thomasz Gniadzdowski3, Christian Müntz1, and Christian Wendisch2 for the HADES collaboration — 1Goethe-Universität Frankfurt am Main — 2GSI Helmholtzzentrum für Schwerionenforschung — 3Warsaw University of Technology
The drift chambers (MDC) of the HADES Experiment at GSI, Darmstadt form the main tracking system of the spectrometer. Being designed more than twenty years ago, we are currently replacing the whole electronics read-out chain with state-of-the-art electronics.
The new analog signal processing is based on the PASTTREC ASIC, originally developed at AGH Krakow for the PANDA Straw Tube Tracker. The digitization of data happens in FPGA-based TDCs before data is sent on an optical link to the event server farm.
The main challenges of the project are the strict spatial constraints given by the experiment setup and the noise sensitivity of the large area gas detectors. In addition, the power consumption needed to be kept low to ease cooling of the electronics.
