TCAD Modeling of Surface Radiation Damage Effects: A State-Of-The-Art Review

Frontiers in Physics, 2021
A comprehensive numerical model which accounts for surface damage effects induced by radiation on silicon particle detectors is presented with reference to the state-of-the-art Synopsys Sentaurus Technology CAD (TCAD) tool.

Silicon detectors for synchrotron radiation digital mammography [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1995
Abstract The knowledge of the dose and of the energy spectrum of the X-rays delivered to the patient during a radiological examination allows in principle the computation of the number of photons per unit surface useful for a good mammography. The film-screen assembly detectors used in the present standard practice require a number of photons per ...

Characterization of Heavily Irradiated Dielectrics for Pixel Sensors Coupling Insulator Applications

Frontiers in Materials, 2022
An increase in the radiation levels during the high-luminosity operation of the Large Hadron Collider calls for the development of silicon-based pixel detectors that are used for particle tracking and vertex reconstruction. Unlike the conventionally used

Radiation damage in silicon detectors [PDF]

Nuclear Instruments and Methods in Physics Research, 1984
Abstract A review is presented of the effects of radiation damage on silicon detectors, which are being considered for high energy physics applications. The main degradation in performance is an increase in leakage current, which can be well characterized by an empirical damage constant for many radiations.

Macroporous silicon membranes as electron and x-ray transmissive windows [PDF]

, 2004
Macroporous silicon membranes are fabricated whose pores are terminated with 60 nm thin silicon dioxide shells. The transmission of electrons with energies of 5 kV-25 kV through these membranes was investigated reaching a maximum of 22% for 25 kV ...

Comparison of Thermal Detector Arrays for Off-Axis THz Holography and Real-Time THz Imaging

Sensors, 2016
In terahertz (THz) materials science, imaging by scanning prevails when low power THz sources are used. However, the application of array detectors operating with high power THz sources is increasingly reported.

Defect Engineering Radiation Tolerant Silicon Detectors [PDF]

Solid State Phenomena, 1997
It is planned to use silicon detectors for many applications at the CERN Large Hadron Collider, where they will be exposed to unprecedented particle fluences. After hadronic irradiation, such detectors exhibit macroscopic changes in their electrical characteristics which lead to a degradation in performance.

TCAD advanced radiation damage modeling in silicon detectors [PDF]

Proceedings of The 28th International Workshop on Vertex Detectors — PoS(Vertex2019), 2020
In this work we present a methodology to develop a surface and bulk TCAD radiation damage effects model which enables a predictive insight into the electrical behavior of novel solid-state detectors up to the particle fluences expected at the end of HL-LHC.
