Description
Modules with a double-sided silicon microstrip sensors are the
back-bone components of the future wide-aperture Silicon Tracking
System of BM@N experiment. The main features of this module are the
fast readout electronics based on STS-XYTER ASIC and the usage of low
mass (0.23% X0) aluminum micro-cables for the transfer of analog
signals from the sensor strips to the input channels of the readout
electronics. The results of tests of the tracking modules with 1 GeV
proton beams at the SC-1000 accelerator at PNPI are presented. Stable
operation of the readout electronics at occupancies, which are close
to the maximum values - 360 kHz sec^-1 cm^-2 was demonstrated. The
Signal-to-Noise ratio for the module is more than 23. The measured
coordinate resolution of the modules within the beam telescope is
17±0.4 μm, and the detector registration efficiency for protons with
energy of 1 GeV is more than 99%.
