Radio-quiet neutron star ten bodies have been proposed as rotation-powered neutron stars that are not visible as radio sources, but are visible as x–ray and gamma ray sources. Indicators that they are indeed neutron stars include them having a high x-ray to lower frequencies emission ratio, a constant x-ray emission profile, and coincidence with a gamma ray source. Quark stars, theoretical neutron star-like objects composed of quark matter, may be radio quiet, according to some theories. More plausibly, however, radio-quiet neutron stars may simply be pulsars which do not pulse in our direction. As pulsars spin, it is theorized they emit radiation from
Canadian Neutron Beam Centre Canadian Neutron Beam Centre The NRC Canadian Neutron Beam Centre (CNBC) is Canada's national user facility that enables researchers to use neutron beams as tools for world-class materials research. The CNBC is located at Chalk River Laboratories, where Atomic Energy of Canada Limited (AECL) owns and operates the National Research Universal (NRU) reactor. CNBC has been a global leader in the development of materials and products for businesses. Like most other neutron beam laboratories, the CNBC operates beamlines as a service to external researchers. In a typical year, about 250 individuals participate in research that relies on access to its
