TPA-TCT -- Two Photon Absorption - Transient Current Technique

Speaker

Moritz Oliver Wiehe (Albert Ludwigs Universitaet Freiburg (DE))

Description

The Transient Current Technique (TCT) has become a very important tool for characterization of unirradiated and irradiated silicon detectors. In recent years a novel method, the Two Photon Absorption - Transient Current Technique (TPA-TCT), based on the charge carrier generation by absorption of two photons, was developed. TPA-TCT proved to be very useful in 3D characterization of silicon devices with unprecedented spatial resolution. Currently the first compact TPA-TCT setup is under development at CERN. The current status of the setup and methods for characterizing the spatial beam profile are presented.
