The ATLAS Pixel detector consists of hybrid pixel modules where the sensitive elements are planar n-in-n sensors and has been operating since 2010.
In order to investigate and predict the evolution of the depletion voltage in the different layers, a fully analytical implementation of the Hamburg model was derived. The parameters of the model, describing the dependence of the depletion voltage...
I will present results of Synopsys TCAD simulations of OVERMOS, a MAPS CMOS detector based on high resistivity substrate. Following a short description of the main features of OVERMOS, I will describe experimental results of initial test structures and comparisons with TCAD simulation results, both for standard and neutron irradiated devices. I will then describe a proposed fabrication of test...
It is widely accepted that implantation profiles in the multiplication layer of Low-Gain Avalanche Detectors (LGAD) constitute a critical feature in view of keeping the gain as low as required by high-energy particle timing measurements. One of the most powerful tools we can use to predict the amount of multiplied charges and then the behavior of LGAD, both before and after irradiation, is the...
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. Coupling of LGAD...
The new LGAD batch with Gallium doping is now in its first experimental stages. Using TCAD Sentaurus we explore the increase in radiation hardness that could be achieved.
