HADES Driftchambers Electronics Upgrade: Power Supply — •Ole J. Artz for the HADES collaboration — Goethe-Universität Frankfurt

The readout electronics of the drift chamber tracking system of HADES will be upgraded in the comming year to allow for handling higher trigger rates in future experiments at SIS18 and SIS100. The upgrade is also aiming at an improved robustness w.r.t. electronic noise and the ability to resolve multiple hits in drift cells.

An important part of this activity is improving the power scheme both w.r.t. load and noise immunity. Due to the sensitivity of the detector, switching voltage regulators can not be installed on the front-end electronics, but need to be placed further away. These regulators will be remotely controllable using an Ethernet-capable microcontroller.

As a side-project, the same controller will be employed for flexible read-out of various sensors for the detectors' gas system.

This work has been supported by BMBF(05P19RFFCA), CremlinPLUS, GSI and HIC for FAIR.
