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 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
