Description
A test beam telescope has been built using the ALIBAVA system to drive its
data acquisition. The basic telescope planes consist in four XYT stations. Each
station is built from a detector board with two 80-micron-pitch sensors,
mounted one in each side and their strips crossing at 90 degrees. The
ensemble is coupled to an ALIBAVA daughter board. These stations act as
reference frame and allow a precise track reconstruction. The system is
triggered by the coincidence signal of the two scintillators located up and down
stream. The telescope can hold several devices under tests. Those may be
mounted on detector boards coupled to the ALIBAVA daughter board.
Each ALIBAVA daughter board (either linked to XYT station or a device under
test) is subsequently read by its corresponding mother board. The acquisition
system can hold up to 16 mother boards. The whole system is controlled by a
master board that synchronizes all the mother boards and collects all the data.
The off-line analysis software has been developed to study the charge
collection, cluster width, tracking efficiency, resolution, etc, of the devices
under test. Moreover, the built-in ALIBAVA TDC allows the analysis of the time
profile of the device signal.
The ALIBAVA Telescope has been successfully operated in two test runs at the
DESY and CERN-SPS beam lines. The complete telescope system will be
described and the preliminary results will be presented.
