Development of a silicon micro-strip detector for tracking high intensity secondary beams

摘要

A single-sided silicon micro-strip detector (SSD) has been developed as a tracking detector for hadron experiments at J-PARC where secondary meson beams with intensities of up to 10~8 Hz are available. The performance of the detector has been investigated and verified in a series of test beam experiments in the years 2009-2011. The hole mobility was deduced from the analysis of cluster events. The beam rate dependence was measured in terms of timing resolution, signal-to-noise ratio, and hit efficiency. This paper describes the detector with its read-out system, details of the test experiments, and discusses the performance achieved.
