A Beam Test Telescope Based On The Alibava Readout System

A telescope for a beam test have been developed. The system is intended to measure the spatial resolution performance of different types of silicon detectors. The telescope has four XY measurement as well as trigger planes (XYT board). It can accommodate up to twelve devices under test (DUT board). The DUT board uses two Beetle ASICs for the readout of chilled DUT, microstrip or pixel silicon detectors. The XYT board triggers on the particle tracks in the beam test. It also measures the track space points using two silicon strip detectors connected to two Beetle ASICs. An Alibava mother board is used to read out and to control each XYT/DUT board from a common trigger signal and clock signal. A master board distributes the trigger, clock and reset signals. It also merges the data streams from up to sixteen Alibava boards. The master board is connected with the DAQ software via 100M Ethernet. Track based alignment software has also been developed for the data obtained with the DAQ software.
