Doping removal—whether acceptor or donor—is a well-known effect of radiation damage in silicon detectors, and has been extensively characterized at the low doping levels typical of conventional silicon substrates. The development of Low Gain Avalanche Diode (LGAD) technology has pushed detailed studies of acceptor removal at high initial concentrations ($> 10^{16}$ at/cm$^3$). With the...

At the High Luminosity Large Hadron Collider (HL-LHC), silicon pixel detectors will be exposed to radiation fluences about 5 to 10 times larger than those experienced by the current innermost pixel layers up to today.
Signal loss will be the main limitation to tracking and vertexing performance due to radiation damage in hybrid pixel detectors, with the increase in leakage current and...

121. A TCAD Simulation Framework for DLTS-based Defect Characterisation in Solid-State Particle Detectors

The increasing radiation levels expected in future high-luminosity collider experiments demand robust predictive models for the design and optimisation of semiconductor particle detectors operating under extreme fluences (above $1 \cdot 10^{16}\,\mathrm{1\,MeV}\,n_{eq}/\mathrm{cm}^{2}$). Although TCAD-based modelling of radiation damage has evolved over the past two decades, a general-purpose...
