Abstract
The readout electronics for the WADES RICH uses new concepts for the data t ransport and a multilevel trigger scheme for online data reduction. We have developed two types of modules for the readout of the RICH detector that i s used for lepton identification in the HADES spectrometer. The first one i s a mixed analog and digital frontend module that converts the charge signa ls 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. (C) 1999 Elsevier Science B.V. All rights reserved.
