New 3He neutron monitor for Chilean Cosmic-Ray Observatories from the Altiplanic zone to the Antarctic zone
(Facultad de Ciencias, 2012)
We present the results of three years of continuous operations and the principal characteristics of our new 3He neutron monitors installed in the Chilean Network of Cosmic-Ray Observatories. During the years 2004 and 2005, ...
New He-3 neutron monitor for Chilean Cosmic-Ray Observatories from the Altiplanic zone to the Antarctic zone.
(CIENCIAS, 2012)
We present the results of three years of continuous operations and the principal characteristics of our new He-3 neutron monitors installed in the Chilean Network of Cosmic-Ray Observatories. During the years 2004 and 2005, ...
Enhancing neutron detection capabilities of a water Cherenkov detector
(Elsevier Science, 2020-03)
In this work we show the neutron detection capabilities of a water Cherenkov detector (WCD) using pure water, as well as an aqueous solution of sodium chloride as the detection volume. The experiments were performed using ...
Detectores de Neutrones de 10B+ZnS(Ag) como alternativa a los detectores de 3He instalados en los Monitores de Radiación tipo Pórtico RPM’s
(Universidad Autónoma MetropolitanaCentro de Investigación y de Estudios Avanzados del Instituto Politécnico Nacional (CINVESTAV), 2016-11)
Los sistemas de detección llamados “Radiation Portal Monitors” RPMs o Monitores de
Radiación tipo Pórtico habitualmente instalados en zonas fronterizas, son un conjunto de
detectores gamma y de neutrones; el uso de ...
10B+ZnS(Ag) as an alternative to 3 He-based detectors for Radiation Portal Monitors
(EDP Sciences, 2017-09-25)
Typical radiation portal monitor systems, RPM, deployed to detect illicit trafficking of radioactive materials include a set of gamma-ray detectors and neutron detectors. Usually the employed neutron detectors are pressurized ...
Observation of intensity of cosmic rays and daily magnetic shifts near meridian 70 degrees in the South America
(Elsevier, 2016)
In analysis of experiments carried during September 2008 using secondary cosmic ray detectors located in Chacaltaya (Bolivia) and Niteroi (Brazil), Augusto et al. (2010) showed an increase in the intensity of charged ...
Study of a 10B + ZnS(Ag) neutron detector as an alternative to 3 He-based detectors in Homeland Security
(ELSEVIER, 2016-11)
The response of a scintillation neutron detector of ZnS(Ag) with 10B was calculated, using the MCNPX Monte Carlo Code. The detector consists of four panels of polymethyl methacrylate (PMMA) and five thin layers of ~0.017 ...
