Application of BM@N Si-Microstrip Detectors at Muon Stand for Testing Straw Detectors

Forward Silicon Detector of the BM@N experiment was used for tests of the straw detector and for the measurement of the straw R – t dependence (straw diameter d = 6 mm) based on cosmic muon tracking by reconstruction software based on the “BmnRoot” framework. The cosmic muon stand consists of scintillators, silicon planes, the straw detector and Data Acquisition System. Silicon planes are based on Double-sided Silicon Strip Detectors (DSSD) with strip pitch 95 μm for p + side and 103 μm—for n + side. The stereo angle between strips is 2.5°. A general view of the stand, a description of silicon planes and first measurement results of the straw R – t dependence are presented.
