چکیده
Neutron imaging is one of the most powerful tools for nondestructive inspection owing to unique characteristics neutron beams, such as high permeability many heavy metals, sensitivity certain light elements, and isotope selectivity a specific nuclear reaction between an neutrons. In this study, we employed superconducting detector, current-biased kinetic-inductance detector (CB-KID) using pulsed source. We delay-line method, spatial resolution with only four reading channels was achieved. also performed wavelength-resolved by time-of-flight method obtained transmission images Gd–Al alloy sample, inside which single crystals GdAl $_3$ were grown, CB-KID. Single well imaged, in both shapes distributions, throughout Al–Gd alloy. identified Gd nuclei via transmissions that exhibited characteristic suppression above wavelength 0.03 nm. addition, notation="LaTeX">$^{155}$ resonance dip, dip structure caused neutrons, observed even when number events summed over limited area 15 notation="LaTeX">$\mu$ m × 12 m. selective Gd, it showed clear distribution range 1 pm.

متن کاملPhase Frequency Detector Using Transmission Gates for High Speed Applications
In this paper a new phase-frequency detector is proposed using transmission gates which can detect phase difference less than 500ps. In other word, the proposed Phase-frequency Detector (PFD) can work in frequencies higher than 1.7 GHz, whereas a conventional PFD operates at frequencies less than 1.1 GHz. This new architecture is designed in TSMC 0.13um CMOS Technology. Also, the proposed PFD a...
متن کاملPrototype developments for a high-resolution neutron detector at RB
A detector for momentum measurements of highenergy neutrons in the energy range 200 MeV to 1000 MeV is being developed for the RB experiment at FAIR. The detection principle is based on a combination of converter material and subsequent detection of charged particles from reactions in the converter material. Multigap Resistive-Plate Chambers (MRPC) are used for the detection of charged particle...
