31.03.2022PhD awarded to Dr. Kevin Thieme

Congratulations to Dr. Kevin Thieme who successfully defended his Ph.D. thesis at the end of March! During his thesis, Kevin worked on the DARWIN demonstrator (Xenoscope) in our laboratory at UZH and on R&D with a small, two-phase xenon TPC. He was involved in designing, building and commissioning a large, full-scale vertical demonstrator for the DARWIN Observatory. Kevin also had leading involvement in the first two-phase xenon TPC operated with a top SiPM array, Xürich, and he analysed the Xürich data with respect to the W-value in liquid xenon. He obtained a value which is lower than the older, standard value used in the literature, but consistent with a more recent value from the EXO-200 collaboration.
