Accelerator-based cold neutron sources and their cooling system.

Neutron Producing Target for Accelerator Based Neutron Capture Therapy*

Pilot innovative accelerator based neutron source for neutron capture therapy of cancer [1] is now on the threshold of its operation at the BINP, Russia. One of the main elements of the facility is lithium target producing neutrons via threshold Li(p,n)Be reaction at 25 kW proton beam with energies 1.915 MeV or 2.5 MeV. In the present report, choice of target is substantiated, the main problems...

Lithium neutron producing target for BINP accelerator-based neutron source.

Pilot innovative accelerator-based neutron source for neutron capture therapy is under construction now at the Budker Institute of Nuclear Physics, Novosibirsk, Russia. One of the main elements of the facility is lithium target, that produces neutrons via threshold (7)Li(p,n)(7)Be reaction at 25 kW proton beam with energies 1.915 or 2.5 MeV. In the present report, the results of experiments on ...

Accelerator based epithermal neutron source for NCT

Nowadays neutron capture therapy looks very promising method of cancer treatment, especially for brain tumors by reason of selective damage cancer cells. Treatment effect of this method based on neutrons nuclear reaction with nuclides B, Gd. These nuclides have high cross-section of interaction with thermal neutrons. Unfortunately, thermal neutrons could enter only in near surface tissue and co...

Cooling Neutron Stars and Super uidity in Their Interiors

Neutron Star Cooling

Observation of cooling neutron stars can potentially provide information about the states of matter at supernuclear densities. We review physical properties important for cooling such as neutrino emission processes and superfluidity in the stellar interior, surface envelopes of light elements due to accretion of matter and strong surface magnetic fields. The neutrino processes include the modif...
