Beam Test Tracking Telescope

---

The Rutgers test beam tracking telescope consists alternating X and Y silicon micro-strip planes (4 each X and Y). A VA2 frontend readout is used to read strip planes. Silicon planes we used were of 50 micron pitch, with an intermediate strip. This allowed to obtain a better than digital resolution resulting less than 2 micron track extrapolation accuracy in the middle of the detector. This tracking telescope have been used in measuring CVD diamond pixel detectors as well as Si pixel sensors developed for the CMS forward pixel detector.

Among my contribution to the tracking telescope are :

• Design and fabrication of hybrid for Si microstrip planes .


• Design and building of VA sequencer and other related DAQ electronics .


• Design and fabrication of numerous other mechanical and electrical components (ie. scintilators, cartridges, circuit boards, mounts, etc...) and the installation and operation of the telescope at CERN and Fermilab test beams.


• Writing tracking software, software alignment of the tracking system using beam test data, and the analysis of data to evaluate the performance of pixel detectors.
