Monolithic circuits for the WA98 lead glass calorimeter

PDF Version Also Available for Download.

Description

Two monolithic circuits developed for readout of a 10,000 element lead glass calorimeter are described. The first contains 8 channels with each channel comprising a charge integrating amplifier, two output amplifiers with gains of one and eight, a timing filter amplifier and a constant fraction discriminator. This IC also contains a maskable, triggerable calibration pulser and circuits needed to form 2 by 2 and 4 by 4 energy sums used to provide trigger signals. The second IC is a companion to the first and contains 16 analog memory channels with 16 cells each, eight time-to-amplitude converters and a 24-channel analog-to-digital ... continued below

The second IC is a companion to the first and contains 16 analog memory channels with 16 cells each, eight time-to-amplitude converters and a 24-channel analog-to-digital converter. The use of the analog memories following the integration function eliminates the need for delay cables preceding it. Characterizations of prototypes are reported, and features included to ease integration if the ICs into a readout system are described.
