Using a handheld gamma-ray detector array and up to four 8 $\mu $ Ci 137 Cs gamma-ray sources, we performed both source-search and source-separation experiments in an indoor laboratory environment

A Plutonium Mass Uncertainty Assessment Using a Cherenkov-Based Neutron Multiplicity Water Detector IEEE Trans. Nucl. Sci. (IF 1.575) Pub Date : 2020-10-09 Alexandra Asghari; Steven Dazeley; Adam Bernstein
We present a new analysis of the sensitivity of a water Cherenkov-based neutron multiplicity counter for nondestructive assay of trace quantities of 240 Pu. The multiplicity counter [water-based neutron detector (WaND)] contains 1.0 m 3 of water doped with 0.2% gadolinium in the form of a gadolinium salt (0.4% GdCl 3 ). It can be used for testing the presence of trace quantities of 240 Pu within a

Effect of the Electric Field Strength on the Energy Resolution of Cr/CdTe/Pt Detectors IEEE Trans. Nucl. Sci. (IF 1.575) Pub Date : 2020-09-23 V. Sklyarchuk; Z. Zakharuk; S. Solodin; A. Rarenko; O. Sklyarchuk; P. Fochuk; A. Bolotnikov; R. B. James
The electrical and spectrometric characteristics of the Cr/cadmium telluride (CdTe)/Pt structure with a metal–semiconductor type rectifying contact, used in X/ $\gamma $ -ray detectors, are investigated. For the detectors fabrication, chlorine-doped CdTe crystals with a resistivity of (3–6) $\times 10^{{9}}\,\,\Omega $ cm at 293 K were used. 137 Cs spectra and their modification by applied voltage

Effects of High-Dose X-Ray Irradiation on the Hole Lifetime in Vacuum-Deposited Stabilized a-Se Photoconductive Films: Implications to the Quality Control of a-Se Used in X-Ray Detectors IEEE Trans. Nucl. Sci. (IF 1.575) Pub Date : 2020-09-14 B. Simonson; R. E. Johanson; S. O. Kasap
Stabilized amorphous selenium (a-Se)-based digital flat-panel X-ray imaging detectors are widely used in modern mammography. The dependence of the hole lifetime, $\tau _{h}$ , in a-Se on high-dose X-ray irradiation under high electric fields is examined. The X-ray-induced effects on the samples were studied using conventional time-of-flight (TOF) and interrupted-field time-of-flight (IFTOF) techniques

A Zynq-Based Flexible ADC Architecture Combining Real-Time Data Streaming and Transient Recording IEEE Trans. Nucl. Sci. (IF 1.575) Pub Date : 2020-11-02 Andrea Rigoni Garola; Gabriele Manduchi; Marco Gottardo; Roberto Cavazzana; Mauro Recchia; Cesare Taliercio; Adriano Luchetta
The RFX-mod2 Nuclear Fusion experiment is an upgrade of RFX-mod, which was shutdown in 2016. Among the other improvements in the machine structure and diagnostics, a larger number of electromagnetic probes (EMs) is foreseen to provide more information about plasma instabilities and to allow an improved real-time plasma control. An analog-to-digital converter (ADC) architecture able to provide, at the

Optimization of Beam Arrival and Flight Time Measurement System Based on Cavity Monitors at the SXFEL IEEE Trans. Nucl. Sci. (IF 1.575) Pub Date : 2020-10-28 Shanshan Cao; Yongbin Leng; Renxian Yuan; Jian Chen
To fully optimize the operation of a high-gain free-electron laser (FEL) facility and to offer opportunities for time-resolved experiments, a highly accurate synchronization between an electron bunch and a seeded laser is required. Thus, a high-precision and high-resolution beam arrival and flight time measurement system is built at the Shanghai soft X-ray FEL (SXFEL) facility. For the SXFEL, a beam

Single-Event Transient Space Characterizations in 28-nm UTBB SOI Technologies and Below IEEE Trans. Nucl. Sci. (IF 1.575) Pub Date : 2020-10-26 Capucine Lecat-Mathieu de Boissac; Fady Abouzeid; Victor Malherbe; Thomas Thery; Gilles Gasiot; Jean-Marc Daveau; Philippe Roche; Jean-Luc Autran
In this article, we present a study of single-event transients (SETs) through an integrated test vehicle. This block was designed and manufactured within two test-chips in 28- and 22-nm fully depleted silicon-on-insulator (FDSOI) advanced technologies. Radiation testing was performed on those test chips in order to characterize SETs. The results are cross-coupled with Monte Carlo simulations and discussed
