Monte Carlo calculations with Geant4 were performed to calculate the response of He-3 proportional counters for neutrons of the energy region of 230 keV – 7 MeV. The results are compared with experimental data obtained by irradiation of the detectors with monoenergetic neutron beams produced by 7Li(p,n)7Be and 2H(d,n)3He reactions in the Tandem accelerator, NSCR Demokritos Athens.

Abstract:

Four cylindrical steel bars of 2 cm diameter and 20 cm height were subjected to compression cycles each of them consisting of a loading phase at fixed stress rate followed by a rapid stress release. Different compression rates were used for the same sample. The area surrounding the loaded samples was monitored in order to check whether ionizing particles were emitted. To this aim, three ZnS(Ag) detectors, a Geiger counter, and some polycarbonate CR39 detectors of alpha particles were used. An 3 He proportional detector of neutrons was also used.

Abstract:

For many years at LLNL, we have been developing time-correlated neutron detection techniques and algorithms for applications such as Arms Control, Threat Detection and Nuclear Material Assay. Many of our techniques have been developed specifically for the relatively low efficiency (a few percent) inherent in man-portable systems. Historically, thermal neutron detectors (mainly 3 He ) were used, taking advantage of the high thermal neutron interaction cross-sections, but more recently we have been investigating the use of fast neutron detection with liquid scintillators, inorganic crystals, and

Very-high-energy (VHE) gamma rays, with energies .<: 1 TeV = 1012 eV, are observed with ground-based telescopes using the atmospheric Cerenkov technique.

Recent advances in this field have been aided by the results from satellite detectors with high-energy (HE) gamma ray 'eyes'.

Abstract:

X-ray spectroscopy is an advantageous tool for investigation of the shift and width of the energy levels in kaonic atoms, evoked due to strong interaction between nucleus and kaon. In order to study the 2p level shift in kaonic 3 He , the X-ray transition 3 p →2 d in liquid kaonic 3 He will be measured with a precision of <2 eV in the E17 experiment at J-PARC. To reach this desired precision, a well designed setup, in-situ calibration and state-of-the-art semiconductor detectors will be used. The idea and the preparation status of the whole setup will be reported in this article.

Specific CCT mode manifesting itself as a rectangular structure in the mass-mass plot of detected fragments was revealed both by neutron gating and direct detection of all three decay partners.

ABSTRACT The merging of double white dwarfs (WDs) may produce the events of accretion-induced collapse (AIC) and form single neutron stars (NSs). Meanwhile, it is also notable that the recently proposed WD+He subgiant scenario has a significant contribution to the production of massive double WDs, in which the primary WD grows in mass by accreting He-rich material from a He subgiant companion. In this work, we aim to study the binary population synthesis (BPS) properties of AIC events from the double WD mergers by considering the classical scenarios and also the contribution of the WD+He subgi

This technique is emerging from soft matter and biology where highly absorbing nuclei, in very small quantities, are used as a label for buried layers. Nowadays, the importance of absorbing layer

Abstract:

The results of the measurements of the neutron and gamma radiation produced in the 9 Be( 3 He,pγ) 11 B and 9 Be( 3 He,nγ) 11 C nuclear reaction at the 2.57 MeV energy of the 3 He ions are represented. The measurements were carried out with organic scintillation detector BC-501A and semiconductor HPGe spectrometers. Gamma-ray spectra were measured at 0°, 30°, 60°, 90° and 120° angles. The shapes of the gamma lines 6.9 MeV from the 9 Be( 3 He,nγ) 11 C reaction and 8.92 MeV from the 9 Be( 3 He,nγ) 11 C were obtained. The angular distribution of protons populating the 8.92 MeV energy level of the

Abstract:

An experiment to search for the bound state of η meson in nuclei has been performed at COSY, Juelich using the ENSTAR detector and Big Karl magnetic spectrometer. Reaction (p,3 He ) on 27 Al target has been used to search for the η-mesic nucleus 25 Mg η in the missing mass distribution from the measured 3 He particles. A preliminary figure of 1.5 nb for the upper limit of the formation cross section of η-nucleus bound state has been determined.

Abstract:

EDS-PIXE is a very useful and easy method for detecting trace elements in ancient materials. However, relatively high continuous background is observed, when old copper alloys are measured under 4 MeV protons. The background makes the detection limits of trace metallic elements such as Au , Ag , As , Sn , Sb and Pb in these alloys worse. The cause of the high background was investigated using a Si ( Li ) detector, a pure- Ge detector and a 3 He neutron counter, and it was found that the continuous background level is correlated with the amount of neutron released from 65 Cu ( p , n )65 Zn reac

Abstract:

Studies of light meson decays are the key experiments for the WASA detector at COSY-Jülich. One of the world largest data samples of the η meson decays have been recently collected in the pd →3 He η and in the pp → ppη reactions. The status of the analysis of various decay channels and the further plans for the light meson decay program are presented.

Abstract:

Abstract Evidence for coseismic temperature rise that induces dynamic weakening is challenging to directly observe and quantify in natural and experimental fault rocks. Hematite (U-Th)/He (hematite He) thermochronometry may serve as a fault-slip thermometer, sensitive to transient high temperatures associated with earthquakes. We test this hypothesis with hematite deformation experiments at seismic slip rates, using a rotary-shear geometry with an annular ring of silicon carbide (SiC) sliding against a specular hematite slab. Hematite is characterized before and after sliding via textural and

Abstract:

A simple model was used to simulate the current pulse induced by charged particles with Si detector. With simulated current shapes of three element groups, H/D/T (6MeV), He-3/He-4 (15MeV) and Li-6/Li-7 (35MeV), three methods of pulse shape analysis (PSA), i.e. the m2-m3 method, the integration method and the second moment method, were compared and analyzed. Their discrimination performance and noise resisting property are investigated. The results show that the charge integration method and the m2-m3 method both have good discrimination performance and noise resisting property. While neither t
