Nuclear Structure Studies Using Gamma-Ray Spectroscopy and Digital Signal Processing,etermination of the chemical and isotopic composition of materials. Semiconductor and scintillation radiation detectors are most commonly caused for this purpose, and both energy and time parameters may need to be determined with high precision, depending on the application. Concurrent high-resoluti

Cascade Gamma Emission Coincidence Tomography,hotons that are coincident in a time window, one can infer the location of the emitting radiopharmaceutical molecule directly from the back-projections of the two photons. This is the working principle of cascade gamma emission coincidence tomography. The advantage of this approach is the coincident

Compton Imaging Systems Based on Semiconductor Detectors,wn as Compton cameras. Compton cameras have several designs but the most common one, consists of a scatterer and an absorber detectors. These detectors are sensitive to the position and energy of the scattered gamma rays. Some of the valuable useful parameters in Compton cameras include efficiency,

Metascintillators for Ultra-Fast Gamma Detectors,atly enhanced when improving detector timing capabilities, due to the availability of time-of-flight information. However, physical barriers related to the characteristics of available organic and inorganic scintillators create a trade-off between photon kinetics and gamma detection efficiency..We i
