content: One signal amplifier on rectangular plastic circuit board. Apparently one of these preamplifiers would have been plugged into one corresponding socket of Mulitwire Proportional Chamber 1989.0050.01.1. A sticker accompanying this object reads "8 wire signals [from associated socket on chamber] get amplified .0002V to .8V" (to output to the computer). Similarly for all sockets of all four chambers in each of the two arms of the spectrometer setup at the Brookhaven Alternating Gradient Synchrotron, which was used to measure electrons and positrons resulting from decay of a hypothesized massive "J" particle.
label: Description
content: Rectangular green plastic circuit board, with electronic components soldered on upper surface. As viewed from front of board: at left end of bottom edge are 12 contact strips, only 8 of which are connected to the circuits. Near the right end of the bottom edge are 10 such contact strips. Protruding from right edge are 10 pairs of short wires, which are inserted into a green plastic connector fitting, which has 9 contact sockets on the other side.
