Dr. Marcus Palm

CTO/Co-founder/Board of Directors - Member

PhD in Applied Physics (Vienna University of Technology, Austria/CERN). MSc in Applied Physics and Electrical Engineering (Linköping University, Sweden). Detector Physicist at CERN 13 years: expertise in hadron therapy design, commissioning, CE-certification of medical devices, development of high performance detector systems, various detection technologies and data analysis. Marcus earned an MSc degree in Applied Physics and Electrical Engineering from Linköping University, Sweden. He joined CERN in 2006 and carried out his master thesis in design, implementation and operation of diamond detectors and electron multipliers for a novel kind of neutrino factory. During 2008-2011, he did a PhD at MedAustron/CERN on performance requirement of the entire beam delivery system from the accelerator to the patient, and translated clinical requirements on dose quality into hardware specifications on different elements. Directly after his PhD, Marcus continued at MedAustron as Systems Engineer in the Medical Frontend-group. He was then responsible for the system architecture of different patient safety systems and subsystem integration. Later, he was also working on system validation of the entire facility as a single medical device, for CE-certification. Before the creation of Terapet, he was the main responsible for two light-based detectors in the Large Hadron Collider (LHC) at CERN.
