Description

I worked with LGAD sensors, since they will be used to upgrade the PPS detector for the HL-LHC. I did experimental work by measuring IV and CV curves of trench-isolated LGADs, discovered that they break, broke them systematically and finally showed that they maybe don't break if all pixels are grounded. I also simulated NIEL curves in order to get a data point for 7TeV protons, discovering along the way that the current method might not be applicable for such high energies. I proposed a new method, that I still need to verify and cross check before claiming that it actually works. I also joined researchers for beamtime and measured the timing performance of LGADs read out by ETROC chips.
