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…
TCAD Parameters for 4H-SiC: A Review
Jürgen Burin, Philipp Gaggl, Simon Waid +2
In this literature review we investigate the permittivity, density-of-state mass, band gap, impact ionization, charge carrier recombination, incomplete ionization and mobility in 4…
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…
From Single Particles to Clinical Beam Rates: A Wide Dynamic Range Beam Monitor
Simon Waid, Philipp Gaggl, Andreas Gsponer +4
Access to high-energy particle beams is key for testing high-energy physics (HEP) instruments. Accelerators for cancer treatment can serve as such a testing ground. However, HEP in…
Observation of Charge Enhancement in forward-biased neutron-irradiated 4H-SiC PiN Detectors in UV-TCT Measurements
Andreas Gsponer, Philipp Gaggl, Jürgen Burin +2
Due to the increased commercial availability, wide-bandgap semiconductors and their radiation hardness have recently received increased interest from the particle physics community…
TCAD modeling of radiation-induced defects in 4H-SiC diodes
Philipp Gaggl, Jürgen Burin, Andreas Gsponer +3
Silicon Carbide (SiC) has several advantageous properties compared to Silicon (Si) that make it an appealing detector material, such as a larger charge carrier saturation velocity,…
