Design and fabrication of a Nano-based neutron shield for fast neutrons from medical linear accelerators in radiation therapy [PDF]
Radiation Oncology, 2020 Background Photo-neutrons are produced at the head of the medical linear accelerators (linac) by the interaction of high-energy photons, and patients receive a whole-body-absorbed dose from these neutrons.

Experimental evaluation of transition rate of sapphire crystal for thermal and fast neutrons using MNSR vertical neutron beam line [PDF]
HeliyonUsing a perfect single crystal as a neutron filter allows us to have a thermal neutron beam with almost no background of fast neutrons. Single crystals of Al2O3 (sapphire) have proven to be effective filters for fast neutrons and are incorporated into ...

Fast and Furious: Fast Neutron Therapy in Cancer Treatment [PDF]
International Journal of Particle Therapy, 2022 Fast neutron therapy has been used for decades. In conjunction with recent advances in photonic techniques, fast neutrons are no longer of much oncologic interest, which is not unequivocally positive, given their undoubted therapeutic value.

On a significant slowing-down of the kinetics of fast transient processes in a fast reactor [PDF]
Nuclear Energy and Technology, 2020 The kinetics of nuclear reactors is determined by the average neutron lifetime. When the inserted reactivity is more than the effective delayed neutron fraction, the reactor kinetics becomes very rapid.

Fast neutron environments. [PDF]
, 2011 The goal of this LDRD project is to develop a rapid first-order experimental procedure for the testing of advanced cladding materials that may be considered for generation IV nuclear reactors. In order to investigate this, a technique was developed to expose the coupons of potential materials to high displacement damage at elevated temperatures to ...
