Compton Suppression System performance evaluation for measurement of VERDI activation detectors
نویسندگان
چکیده
The VERDI detector was developed for accurate neutron measurements in the plasma-facing modules of a tokamak. It comprises low activation capsule, capable to withstand harsh conditions fusion environment, containing defined mass metallic foils. fluence and energy spectrum are derived by analysis gamma lines produced elements. In this work, use Compton Suppression System (CSS) is investigated aiming enhance sensitivity analysis. CSS consists 40% HPGe primary coupled set NaI secondary detectors. apparatus discard signals simultaneously recorded on both detectors, thus lowering continuum. detectors were irradiated at Joint European Torus (JET) during 2019 Deuterium-Deuterium (DD) campaign. performance studied calculating peak continuum suppression factors. advantage introduced suppressed spectrometry each nuclide interest explored suitability system discussed.

Fuzzy analytical network process logic for performance measurement system of e-learning centers of universities
This paper proposes an efficient performance measurement system to evaluate the excellence of e-learning centers of universities. The proposed system uses the analytic network process (ANP) as an effective multi-criteria decision making (MCDM) method and its fuzzy mode to respond to uncertainties in judgements. This system also needs a targeted and systematic criteria set which is collected thr...

Slow coincidence circuits for the anti-coincidence measurements have been considered for use in Compton suppression technique. The simplified version of the slow circuit has been found to be fast enough, satisfactory and allows an easy system setup, particularly with the advantage of the automatic threshold setting of the low level discrimination. A well-type NaI detector as the main detector s...
متن کاملPerformance Evaluation of Color Based Edge Detectors
This paper evaluates the performance of the color based edge detection techniques. As known in prior the color images provides more information than the gray scale images, 90% of the edges are same in both type of images but 10% edges cannot be detected in gray images. Therefore color edge detection may improve the edge clarity further and also avoids false edges. The overall purpose of this pa...
