Description
The Two Photon Absorption – Transient Current Technique (TPA-TCT) uses fs-pulsed infrared lasers, with photon energies below the silicon band gap. Excess charge carriers are generated mainly in a small volume (approximately 1µm × 1µm × 20µm) around the focal point of the laser beam, enabling resolution in all three spatial directions. Following the initial success of the method, a compact TPA-TCT setup was developed at CERN. The current setup status, first measurements on LGAD sensors with focus on the gain suppression mechanism, measurements on non-irradiated PIN diodes, and Single Event Effect (SEE) studies in a RD53B chip will be presented.
