Neutron star concluded that the radiation comes from a neutron star at the stage of accretion. In 1967, Jocelyn Bell Burnell and Antony Hewish discovered regular radio pulses from PSR B1919+21. This pulsar was later interpreted as an isolated, rotating neutron star. The energy source of the pulsar is the rotational energy of the neutron star. The majority of known neutron stars (about 2000, as of 2010) have been discovered as pulsars, emitting regular radio pulses. In 1971, Riccardo Giacconi, Herbert Gursky, Ed Kellogg, R. Levinson, E. Schreier, and H. Tananbaum discovered 4.8 second pulsations in an X-ray source in the constellation
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
