Description:
This slender device looks very much like a PC computer card, with a similar power connector at one of its ends. It is made of a large circuit board, the chips produced by Texas Instrument and interconnected with small wires instead of integrated circuits (as such circuit board cards later were). It has no side panels, and was most likely used in a specially designed bin.

FunctionWhen a high energy beam of particles collided with a target, it triggered thousands of events and scattered particles and photons. These were picked up by detectors, which in turn sent electrical signals (or pulses) to a wide assortment of logical devices for analysis. Logic instruments included count-registers (or scalers), which counted up the events; pulse height analyzers (PHA), which selected and sorted pulses that fit within certain sized windows; and coincidence counters, which recorded simultaneous events.
This device was used to generate regular frequency signals that were then used in instruments and various experimental purposes.

Curatorial RemarksIt was probably shop-built at Harvard following CAMAC standards.
