WebThe attenuation of photons by the Marinelli beaker and the detector cap materials is also calculated. In the experiments gamma aqueous sources containing several radionuclides covering the energy range from 60 to 1836 keV were used. By comparison, the theoretical and experimental full-energy peak efficiency values are in good agreement. WebJan 25, 2024 · Peaks occur on summer afternoons, generally between 3 and 7 PM," she said. "Envision a person coming home from work, discovering that the home is warm and turning on the AC. Multiply that by thousands and thousands of customers doing the same thing." Heating homes, of course, also requires energy, particularly in colder parts of the …

Development of program DETSIM to simulate detector

WebThe present analysis employ the full energy peak (FEP) efficiency, ingeniously determined using a standard 152 Eu point source. From combined experiment and Monte Carlo simulation, it has been established that, the FEP efficiencies of the detector for a 200 L cylindrical sample can be well reproduced using a point source. WebThe simulated full-energy peak efficiency for noncoincidence /sup 137/Cs gamma rays agreed with the measured value to within 2%, but the simulated total efficiency is about 8% lower than the measured value for 662 keV. A /sup 60/Co point source was placed in five positions above along the center line of the detector from 0.6 to 14.2 cm. infratech 17-1015 bulb

WebA full energy peak is produced from events resulting in total absorption. It can involve Compton scattering and pair production as well as photoelectric absorption. The single peak in the detected energy spectrum appears at the total electron energy corresponding to the energy of the incident gamma ray E g. WebThis paper presents a Monte Carlo method to obtain the full energy peak efficiency (FEPE) curve for a High Purity Germanium (HPGe) detector, as it is difficult and time-consuming to measure the FEPE curve experimentally. The Geant4 simulation toolkit was adopted to establish a detector model since d … WebApr 1, 2013 · The full energy peak efficiency (FEPE) of two γ detectors by using radioactive parallelepiped sources is computed using a new analytical approach. The approach based on the efficiency transfer method… Expand USING THE EFFICIENCY TRANSFER METHOD TO CALCULATE THE ( FEPE ) FOR COMBINATION OF TWO γ … mitchell robinson state board
