State-of-the-art neutron-sensitive Anger camera systems have been produced to meet the experimental challenges of scientists in geology and biology and other fields for experiments at the Spallation Neutron Source facility(SNS). Rate capability for each neutron Anger camera module in a system will exceed 25,000 neutron detections per second, with detection efficiency at 50 percent for 0.05 eV neutrons...
In recent years a great deal of attention was given to the Hamamatsu Position Sensitive PMTs, due to their suitability for building compact and high resolution gamma cameras. In this framework a great number of solution was proposed for the readout, that vary from the analog readout made with a resistive chain, in some cases including a hardware threshold, to fully digital readouts that read each...
In a preceding work a new compact gamma camera based on the Hamamatsu H8500 PSPMT and on a custom developed electronics was presented. The core element of such electronics is a microcontroller that operates the transfer of the sampled data to a PC using a USB link in full speed modality. This transfer utilizes on one side a firmware that controls the operation performed by the microcontroller and...
