Stereo: cylindrical drift chamber for muon decay experiments at LAMPF

PDF Version Also Available for Download.

Description

A stereo, cylindrical drift chamber has been built for use in a search for rare decay modes of the muon at LAMPF. This chamber (part of the Crystal Box detector) has 728 cells on 8 concentric annuli at alternating angles of 10/sup 0/ to 16/sup 0/ from the chamber axis and with radii from 105 to 220 mm. The basic cell cross section is (9 x 10) mm/sup 2/ and the inter-layer spacing is 4.7 mm. Preliminary results show the single-wire efficiencies to be greater than 99%. Based on results obtained from prototype chambers, we hope to achieve 170-..mu..m resolution ... continued below

Based on results obtained from prototype chambers, we hope to achieve 170-..mu..m resolution (including multiple scattering) when TDC offsets and sense-wire locations found in a careful inspection of the endplates are added to the track-finding algorithm.
