Photon Propagation Around Compact Objects and the Inferred Properties of Thermally Emitting Neutron Stars [PDF]

open access: yes, 2000
Anomalous X-ray pulsars, compact non-pulsing X-ray sources in supernova remnants, and X-ray bursters are three distinct types of sources for which there are viable models that attribute their X-ray emission to thermal emission from the surface of a ...

Photon Splitting in Magnetar Models of Soft Gamma Repeaters [PDF]

open access: yes, 1995
The recent association of soft gamma repeaters (SGRs) with counterparts in other wavebands has sparked much interest in these sources. One of the recent models for these objects is that they originate in the environs of neutron stars with fields much ...

Development of new small-angle neutron scattering geometry with ring-shaped collimated beam for compact neutron source [PDF]

open access: yesEPJ Web of Conferences, 2020
Small-angle neutron scattering (SANS) is an important tool to investigate material properties in nanometer to micrometer scale. The opportunity to conduct SANS experiments is, however, limited because of the low number of available SANS beam lines ...

Design optimization and performance capabilities of the fast neutron imaging telescope (FNIT) [PDF]

open access: yes, 2007
We describe the design optimization process and performance characterization of a next generation neutron telescope, with imaging and energy measurement capabilities, sensitive to neutrons in the 1-20 MeV energy range.

Towards High-Repetition-Rate Fast Neutron Sources Using Novel Enabling Technologies

open access: yesInstruments, 2021
High-flux, high-repetition-rate neutron sources are of interest in studying neutron-induced damage processes in materials relevant to fusion, ultimately guiding designs for future fusion reactors.

Short Gamma Ray Bursts as possible electromagnetic counterpart of coalescing binary systems [PDF]

open access: yes, 2010
Coalescing binary systems, consisting of two collapsed objects, are among the most promising sources of high frequency gravitational waves signals detectable, in principle, by ground-based interferometers.

R-modes in accreting and young neutron stars [PDF]

open access: yes, 2001
Recent work has raised the exciting possibility that r-mode pulsations (Rossby waves) in rotating neutron star cores may be strong gravitational wave sources.

Energy and target material dependence of the neutron yield induced by proton and deuteron bombardment [PDF]

open access: yesEPJ Web of Conferences, 2020
The neutron yield for compact accelerator driven neutron sources depends on the target material, the ion type and its energy. When such sources are operated with low energy proton beams below 30 MeV, typical target materials are lithium and beryllium ...
