Alignment Method for the Mark II Silicon Strip Vertex Detector Using an X-ray Beam

摘要

A silicon strip vertex detector consisting of 36 independent detector modules is being constructed for use in the Mark II detector at the SLAC Linear Collider. This paper describes a method for determining the relative alignment of the modules to a precision better than the 5 mu m intrinsic resolution of the detectors. The basic procedure involves moving the vertex detector by known amounts through a fixed, collimated x-ray beam, and using the beam position reconstructed from the detected signals to determine the relative positions and orientations of the modules. Results from tests of the method on a subset of detectors are presented. 5 refs., 11 figs.
