Astrophysical fluid dynamics she pulls in her arms. These stars gradually slow down over the eons, but those bodies that are still spinning rapidly may emit radiation that from Earth appears to blink on and off as the star spins, like the beam of light from a turning lighthouse. This "pulsing" appearance gives some neutron stars the name pulsars. After spinning for several million years pulsars are drained of their energy and become normal neutron stars. Few of the known existing neutron stars are pulsars. Only about 1,000 pulsars are known to exist, though there may be hundreds of millions of old neutron
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
