Boron Neutron Capture Therapy: Clinical Application and Research Progress

Current Oncology, 2022
Boron neutron capture therapy (BNCT) is a binary modality that is used to treat a variety of malignancies, using neutrons to irradiate boron-10 (10B) nuclei that have entered tumor cells to produce highly linear energy transfer (LET) alpha particles and ...

Thermonuclear Burning on the Accreting X-Ray Pulsar GRO J1744-28 [PDF]

, 1996
We investigate the thermal stability of nuclear burning on the accreting X-ray pulsar GRO J1744-28. The neutron star's dipolar magnetic field is 50 years.

Neutron imaging and tomography with MCPs

, 2017
A neutron imaging detector based on neutron-sensitive microchannel plates (MCPs) was constructed and tested at beamlines of thermal and cold neutrons. The MCPs are made of a glass mixture containing B-10 and natural Gd, which makes the bulk of the MCP an
