| Abstract: |
Improved multiwire chamber having means for resolving the left/right ambiguity in the location of an ionizing event. The chamber includes a plurality of spaced parallel anode wires positioned between spaced planar cathodes. Associated with each of the anode wires are a pair of localizing wires, one positioned on either side of the anode wire. The localizing wires are connected to a differential amplifier whose output polarity is determined by whether the ionizing event occurs to the right or left of the anode wire.

What is claimed is:
1. An improved multiwire chamber for the detection and localization of ionizing radiation and having a plurality of anode wires wherein the improvement comprises:
- (a) a pair of localizing wires spaced from substantially parallel to and coextensive with one of said anode wires, one wire of said pair being positioned on either side of said anode wire; and,
- (b) means for determining the difference in signal between the wires of said pair caused by an ionizing event, whereby the ambiguity as to whether said event occurred to the right or left of said anode wire may be resolved.
