Description
The TelePix is a HV-CMOS based upgrade for for the EUDET-style tele- scopes within the DESY II Test Beam facility. The fast monolithic sensor will provide region of interest triggering and precise track timing, overcoming ambi- guities provided by multiple particles transversing the telescope within a single readout frame, which lasts up to 230μs for the MIMOSA26-based telescopes. At current beam intensities, this leads to an average of 6 tracks per event.
Within the project, the summer student will work on laboratory character- isation of the final chip to be deployed at the test beam. The main objective is to correct for pixel-to-pixel fluctuations by adjusting the individual thresh- old voltage per pixel, the so-called trimming. A very homogeneous response to charge is essential to provide stable and precise timing, two core features of a timing plane. These studies can be done with an oscilloscope and single pixels or with a digital data stream for all pixels in parallel.
The student will work within the existing DAQ and implement the required routines to calibrate the sensors and analyse the obtained data. If possible, the influence of the trimming on the timing will be studied at the DESY II Test Beam facility.
