Sum and buffer amplifier for lead-glass barrel calorimeter in the TOPAZ detector

Conference · · IEEE Trans. Nucl. Sci.; (United States)
OSTI ID:6937517
Analog sum and buffer amplifiers have been developed to provide a fast trigger signal from the lead-glass electromagnetic calorimeter in the TOPAZ detector for TRISTAN e/sup +/e/sup -/ collider experiments at KEK. The total kick-back noise from the 4300 channel gate signals of the LeCroy FASTBUS ADC 1885N has been suppressed to less than 40 mV (equivalent to a 0.4 GeV electron signal). The performances of the analog sum and buffer amplifiers that have been developed are described.
