Multiwire position readout system

Multiwire position readout systems have been used for a number of years with proportional counter detectors (67, 68). Adaptations of this method have proved very successful in imaging applications with MCP s (1, 69-71). A typical arrangement (Figure 10) is described by Knapp (69) and consists of two planes of closely spaced wires. Each wire is 0.1 mm in diameter and individual wires are spaced at 0.2 mm intervals with a gap on the order of the wire spacing between the two planes. The wires in the two planes run orthogonal to each other to permit determination of both the x and y coordinates of an event. Resistors interconnect the wires in each plane and preamplifiers are connected to every eighth wire. Thus, a readout system of 130 + 130 wires, for example, requires 16 + 16 amplifiers.
