Status of upgrading the HADES tracking system frontend electronics — •Christian Wendisch for the HADES collaboration — GSI Helmholtz-Zentrum Darmstadt

HADES is one of the running experiments for FAIR phase 0 at SIS-18 (GSI Darmstadt). It is planned to continue running until being setup in the CBM cave for SIS-100 experiments. In the course of these plans an upgrade of the 20 years old frontend electronics of the tracking system is being conducted to further imrove the sensitivity the 24 drift chambers. For the analog part the PASTREC ASIC will replace the ASD8 chips employed so far. PASTREC was originally developped for straw tubes at AGH Krakov. A series of test campaigns has meanwhile been conducted to validate this ASIC for drift chambers, recently at COSY (Jülich). This report will present the status of this project with a focus on the latest test beam results.
