Precise efficiency calibration of an HPGe detector: source measurements and Monte Carlo calculations with sub-percent precision.
نویسندگان
چکیده
With the goal of measuring precise gamma-ray intensities for short-lived (< 5 s) accelerator-produced activities, we have calibrated the efficiency of an HPGe detector between 53 and 1836keV to sub-percent precision with a combination of source measurements and Monte Carlo calculations. Using known or independently measured detector dimensions, we have achieved both relative and absolute agreement (the latter, to 0.1%) between the calculated and measured efficiencies with only two adjustable detector parameters, the thicknesses of the contact dead layers.

The use of Geant4 for simulations of a plastic β-detector and its application to efficiency calibration
Precise β-branching-ratio measurements are required in order to determine ft-values as part of our program to test the Electroweak Standard Model via unitarity of the Cabibbo-Kobayashi-Moskawa matrix. For the measurements to be useful in this test, their precision must be close to 0.1%. In a branching-ratio measurement, we position the radioactive sample between a thin plastic scintillator used...

The Monte Carlo method was used to determine full energy efficiency of a high-purity germanium (HPGe) coaxial detector within an energy range of 53.2-2614 keV. Also, measurement was carried out for a standard Marinelli beaker of 600cm3, which was placed into the reference material of mixed gamma. The plot of the experimentally derived effic...

Calibrations of an HPGe detector were made with respect to photon energy and angle of incidence for the use in field gamma spectrometry. The same detector was modelled in MCNP4C and simulated. This revealed some significant differences between the theoretical (simulated) efficiency and the measured efficiency of the detector, especially at lower energies. In order to investigate the reason for ...
