Low-Gain Avalanche Detector (LGAD) has become an attractive candidate for ultra-fast silicon detectors. TCAD simulations are playing an increasingly important role in optimizing the LGAD design configurations. A few TCAD studies have indicated a disagreement between the simulated and the measured charge collection, even in the non-irradiated LGADs. In simulations, the impact ionization models...
The ATLAS ITk strip sensors are n-on-p sensors with thousands of strips, designed for the ATLAS tracker upgrade for the High-Luminosity LHC and built to withstand extreme radiation levels, up to a 1 MeV neutron equivalent fluence of 1.6×1016/cm2. Developing precise models to understand sensor performance at the device level throughout their operational lifespan is essential for optimizing...
The ATLAS ITk-Strip detector is a planned tracker upgrade for the High-Luminosity LHC which utilizes n+-in-p silicon sensors fabricated by Hamamatsu Photonics with 300 μm signal-generation thickness and approximately 75 μm strip pitch. The sensors must withstand severe irradiation over their operational lifetimes, corresponding to fluences of up to 1.6x10$^{16}$ 1-MeV neq/cm$^2$, with...
A very promising candidate for a more power efficient (e.g., in power electronics) replacement of Silicon is the wide band gap material 4H-SiC. To describe its physical properties in Technology Computer-Aided Design (TCAD) simulations many models with accompanying parameters have been proposed. Often these contradict each other which makes it challenging to identify a suitable initial set of...
SiC detector can work stably for a long time in extreme environments with high temperature and strong irradiation because of its high electron saturation drift rate, high thermal conductivity, high breakdown voltage and strong irradiation tolerance. RAdiation SEmi-conductoR is now developing the full process simulation of various SiC detector like PIN, LGAD and strip detector. Not only the...
Allpix Squared is a versatile open-source simulation framework for semiconductor detectors, and was presented at the last DRD3 week. The framework enables detailed end-to-end simulations of pixellated sensor setups for several detector types, semiconductor materials, and geometries for a variety of applications. It also takes advantage of multi-processor architectures for fully parallel event...
