The digital data acquisition chain and the cosmic ray trigger system for the SLD Warm Iron Calorimeter
The entire data-acquisition chain, from the custom-made front-end electronics to the Fastbus readout and data-reduction module, for the digital readout of the SLD limited streamer tube Warm Iron Calorimeter and Muon Identifier is described. Also described is a Fastbus Cosmic Logic Unit being developed to achieve the capability of reading cosmic ray events, also during the inter-crossing time, for apparatus monitoring and calibration purposes. 9 refs., 9 figs.
Tests of the SGS D779 based readout electronics for the SLD limited streamer tube strips
A study has been made of the properties of the SGS D779-based readout electronics for limited streamer tubes, both with pulses from a pulse generator and with strip pulses from the actual chambers to be used in the SLD detector. To accommodate the special requirements of the SLD detector, a hybrid circuit has been developed and tested that is capable of operating with pulses from the strips of tubes operated below the limited-streamer-node voltages. >
The NUSEX detector
Abstract We present in this paper the characteristics, trigger system and performance of the NUSEX detector, designed to study nucleon stability, running in the Mt. Blanc laboratory.
