Two pad sensors of high-flux CdZnTe grown by Redlen Technologies with different anode metallization (platinum and titanium-gold) were characterized under direct X-ray beam in P07 beamline at Petra III, during 40-bunch mode operation. A Transient Current Technique (TCT) readout setup from the University of Hamburg [1] was used, with a homemade Bias-T, a Femto 40 dB 2GHz amplifier and a...

The High-Luminosity LHC upgrade will require detector systems capable of operating in unprecedented particle rates and radiation environments. To meet these challenges and maintain efficient muon triggering and reconstruction, new Gas Electron Multiplier (GEM) ME0 detectors will be installed in the forward region of the CMS experiment, complementing the already installed GE1/1 GEM detectors...
