Spectacular - A Modular DAQ System for Microdosimetry
Matthias Knopf, Simon Waid, Daniel Radmanovac +8
Particle therapy using light ions like protons, helium ions or carbon ions enables precise tumor targeting with enhanced biological effectiveness while minimizing damage to healthy…
A frontend ASIC for Microdosimetry
Simon Waid, Matthias Knopf, Giulio Magrin +6
Recent clinical evidence shows a correlation between linear energy transfer (LET) and tumor control in carbon ion radiotherapy. This prompts the direct inclusion of LET into the tr…
Measurements of the micro-spill structure of medical cyclotron and synchrotron beams and its impact on pulse pileup
Matthias Knopf, Simon Waid, Stefan Gundacker +10
Detector characterization and instrumentation testing are often performed at cyclotron and synchrotron facilities, many of which were originally developed for medical applications…
In-situ Radiation Damage Study of Silicon Carbide Detectors Subjected to Clinical Proton Beams
Daniel Radmanovac, Andreas Gsponer, Simon Waid +5
Silicon carbide (SiC) planar PiN diodes from two different manufacturers were irradiated with 252.7 MeV protons from a medical synchrotron. Over the course of two 8h irradiation sh…
Design and simulation of a 4H-SiC low gain avalanche diode with trench-isolation
Sebastian Onder, Philipp Gaggl, Jürgen Burin +6
We present the design and simulation of a 30 thick 4H-SiC Low Gain Avalanche Diode (LGAD) optimized for high-voltage operation. A 2.4 thick epitaxiall…
Extraction of Electron and Hole Drift Velocities in thin 4H-SiC PIN Detectors using High-Frequency Readout Electronics
Andreas Gsponer, Sebastian Onder, Stefan Gundacker +5
Silicon carbide (SiC) has been widely adopted in the semiconductor industry, particularly in power electronics, because of its high temperature stability, high breakdown field, and…
