Novel Photon Detectors
- Daniel Weatherill
Silicon Photomultipliers (SiPMs) are solid-state single photon sensitive detectors that show excellent performance in a wide range of applications. In FBK (Trento, Italy), we developed a position sensitive SiPM technology, called “linearly-graded” (LG-SiPM), which is based on an avalanche-current weighted-partitioning approach. It shows position reconstruction resolution below 250 μm on an 8x8...
With a low energy pinhole gamma camera, spatial resolution is mainly determined by the intrinsic spatial resolution of the imaging detector, pinhole diameter and magnification ratio of the collimator. However the pinhole diameter was so far limited to around 1 mm due to the manufacturing difficulty of tungsten. To overcome the limitation of the spatial resolution of the pinhole gamma camera,...
