notes: label: Description
content: A rectangular circuit board bearing on each side a grid of fine wires with solder joints and pin connections. From one end extend 32 black insulated wires formed into two tied bundles of 16 each, 90 inches long. The bundles are wrapped at intervals with black tape and with masking tape near the ends. The ends of the wires in each bundle emerge from their black sheaths, pass through short translucent plastic tubes, and enter a socket connector fitting. The fine wires running parallel to the length of the board have yellow insulation; the wires perpendicular to these are in eight sets on each side of the board. One set on each side has brown insulation; another, red insulation, and the remaining twelve appear as bare copper.
label: Description
content: The wires of all 16 sets terminate in connector strips along one edge of the board. On the opposite edge is a green plastic pin socket fitting . At two corners are wide copper strips folded around on each side of the board; these are soldered to strips of different metal.
label: Description
content: A complete spark chamber spectrometer system consists of a homogeneous magnet containing wire spark chambers with magnetic core readout. Within a spectrometer assembly, each wire chamber is connected to its corresponding core memory plane. The core planes must be located outside the spectrometer magnet. For technical details see B. A. Sherwood, Phys. Rev. 156, 1475 (1967).
