Low Gain Avalanche Detectors (LGAD) are part of family of Avalanche Photodiodes but have only small gain of an order of magnitude. LGAD’s have been shown to have a very fast response time, order of picoseconds, which can make them useful in many applications, including concurrent excellent time and position resolution tracking for particle physics and synchrotron applications.

We present a program for fast calculation of capacitances in planar silicon pixel (strip) sensors, based on a 3D (2D) numerical solution of the Laplace equation. A comparison between calculated capacitances and measurements on silicon strip sensors, along with simulation results obtained with the TCAD Sentaurus suite are presented. The validity of 2D calculations is checked with measurements...
The understanding of the weighting field of irradiated silicon sensors is essential for calculating the response of silicon detectors in the radiation environment at accelerators like at the CERN LHC. Using 1-D calculations of non-irradiated pad sensors and 1-D TCAD simulations of pad sensors before and after irradiation, it is shown that the time-dependence of the weighting field is related...
Garfield++ is a toolkit for the detailed simulation of particle detectors based on ionization measurement in gases or semiconductors. After a brief introduction to the program, ongoing work on the implementation of the simulation of induced currents using time-dependent weighting fields is presented.
