Versatile, Modular Readout System for CAMAC Scalers

A display and readout system for CAMAC scalers will be described which has been in use at SLAC for over a year. Flexibility and versatility are the keynotes of the system, which includes a modular quad display unit employing highly readable Nixie tubes. Other units which may be connected to the expandable bus include an X-Y scope display and a preset count module. The system employs a simple, but versatile CAMAC crate controller. Capability for connection to computers is included, and the system has been interfaced to several different computers.
