A system for in-vivo tracking of 192Ir source during high dose rate or pulsed dose rate brachytherapy treatment was built using 1 mm thick silicon pad detectors as image sensors and knife-edge lead pinholes as collimators. With source self-images obtained from a dual-pinhole system location of the source could be reconstructed in three dimensions in real time. The system was tested with 1 Ci 192Ir...
A Transient Current Technique (TCT) utilizing IR laser with 100 ps pulse width and beam diameter of FWHM=8 ??m was used to evaluate non-irradiated and irradiated p-type silicon micro-strip detectors. The beam was parallel with the surface and perpendicular to the strips (Edge-TCT) so that the electron hole pairs were created at known depth in the detector. Induced current pulses were measured in one...
Polycrystalline CVD (pCVD) diamond detectors are a viable candidate for the innermost tracking layer of experiments at the SLHC, where lifetime fluences are expected to exceed 1016 particles/cm2. Irradiation data of diamonds in this fluence range are scarce, and mostly rely on high-energy protons. According to recent NIEL simulations radiation damage induced by fast reactor neutrons might be representative...
