A slow control and TDC calibration system for the HADES RICH upgrade * — •Adrian Amatus Weber1, Peter Zumbruch2, and Jan Michel3 for the HADES collaboration — 1Justus-Liebig-Universität Gießen — 2GSI Darmstadt — 3Goethe-Universität Frankfurt
The HADES experiment is a high resolution dilepton spectrometer at the SIS18 accelerator of GSI. One of the goals of the Ring-Imaging Cherenkov Detector (RICH) is to identify electron-positron pairs. To enhance the detector performance new multianode photomultipliers from the CBM-collaboration will be used to replace the existing gaseous photo detectors.
Therefore a new EPICS based slow control system is being developed. This system is used to control the TDK Lambda low voltage and the ISEG high voltage power supplies of the RICH detector. It is also used for temperature and humidity monitoring inside and outside the detector with DS18B20 and HDC1000 sensors.
The readout of the RICH detector is done by DiRICH modules. The modules consist of FPGA based TDCs. To cope with high time precision, an online calibration will be implemented. The status of this work will be shown.
