Neutron star between 10 and 10 (100 million to 1 quadrillion) times as strong as that of the Earth. The gravitational field at the neutron star's surface is about (200 billion) times that of the Earth. As the star's core collapses, its rotation rate increases as a result of conservation of angular momentum, hence newly formed neutron stars rotate at up to several hundred times per second. Some neutron stars emit beams of electromagnetic radiation that make them detectable as pulsars. Indeed, the discovery of pulsars by Jocelyn Bell Burnell in 1967 was the first observational suggestion that neutron stars exist. The
Canadian Neutron Beam Centre suite of 6 beamlines at the CNBC. The neutron beam laboratory known as Canadian Neutron Beam Centre was transferred from AECL to the National Research Council in 1997. The NRU reactor, closed in March 2018, was a multi-purpose research reactor that supported science and industry in three areas simultaneously: 1. It was Canada's only major neutron source, supplying neutrons for the CNBC. 2. It was Canada's only major materials testing reactor, supporting nuclear energy research and development. 3. It was one of the two largest global producers of medical radioisotopes. Canadian Neutron Beam Centre The NRC Canadian Neutron Beam Centre
