Abstract :
The readout electronics for the HADES RICH uses new concepts for the data transport and a multilevel trigger scheme for online data reduction. We have developed two types of modules for the readout of the RICH detector that is used for lepton identification in the HADES spectrometer. The first one is a mixed analog and digital frontend module that converts the charge signals from the detector to digital data words. The second module controls the digital readout of the frontend modules and the transport of the event data to a VMEbus memory.
