Prospect of ultrahigh-resolution fast neutron absorption spectroscopy based on a laser plasma electron accelerator

Autor: Wen-Zhao Wang, Jie Feng, Xiao-Peng Zhang, Yao-Jun Li, Wei-Jun Zhou, Wen-Chao Yan, Guo-Qiang Zhang, Chang-Bo Fu, Li-Ming Chen

Publikováno v: High Power Laser Science and Engineering, Vol 12 (2024)

Fast neutron absorption spectroscopy is widely used in the study of nuclear structure and element analysis. However, due to the traditional neutron source pulse duration being of the order of nanoseconds, it is difficult to obtain a high-resolution a

Amplitude of One-Minute Fluctuations of Secondary Cosmic Rays as a Marker of Environmental Factor Determining Ultradian Rhythms in Body Temperature of Laboratory Rats

Autor: M E Diatroptov, M A Diatroptova

Publikováno v: Bulletin of Experimental Biology and Medicine. 172:105-110

The study examined association between oscillations of body temperature of laboratory Wistar rats maintained under constant illumination with the amplitude of fluctuations of secondary cosmic rays reported by neutron count rate provided by neutron mo

Studying the Effect of Meteorological Parameters on the Concentration of Thermal Neutrons, Based on Data from the NEUTRON Setup

Autor: P. S. Kuzmenkova, D. M. Gromushkin, S. Mechraoui, L. Bouchama, Z. T. Izhbulyakova, F. A. Bogdanov, A. N. Dmitrieva

Publikováno v: Bulletin of the Russian Academy of Sciences: Physics. 85:1187-1190

The effect meteorological parameters have on the concentration of thermal neutrons is studied using data from the NEUTRON setup in the period May 2015 to February 2019. Daily and seasonal variations in the neutron count rate are obtained. Such variat

Prediction of new perforation intervals in a depleted reservoir to achieve the maximum productivity: A case study of PNN logging in a cased-well of an Iranian oil reservoir

Autor: Mahdi Rastegarnia, Amir Naghibi, Ali Sanati, Shahab mohamadi nafchi, Saeed Zaker, Soheila Bagheri

Publikováno v: Petroleum, Vol 6, Iss 2, Pp 170-176 (2020)

Pulsed neutron-neutron (PNN) logging is based on emitting neutrons into the near-wellbore zone and computing the neutron count decay due to scattering and capturing. The main application of this logging tool is to determine the current oil saturation

Autor: A. Smejkal, Peter Schwalbach, Jianwei Hu, Stefano Vaccaro, D. Wiarda, J. Peterson, A. Tomanin, P. De Baere, Ian C Gauld, Anders Sjöland, S.J. Tobin

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 888:202-217

The Fork detector is widely used by the safeguards inspectorate of the European Atomic Energy Community (EURATOM) and the International Atomic Energy Agency (IAEA) to verify spent nuclear fuel. Fork measurements are routinely performed for safeguards

Thermal Neutron Cross Section Logging based on compensated neutron logging

Autor: Wensheng Wu, Ruigang Wang, Xinyue Fu, Yunlong Ge, Liuqiong He

Publikováno v: Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine. 166

In this paper, the compensated neutron logging is transformed into the Thermal Neutron Cross Section Logging (TNXS) to improve the application effect. Because the compensated neutron logging measures the neutron count, TNXS cannot be directly measure
