The pulsed subcritical amplifier of neutron flux driven by high-intensity neutron generator

Investigation of neutron flux by thermoluminescence dosimeters in the neutron-gamma mixed field

Introduction: Neutrons have many applications in various fields, such as medicine. The important application of neutron in medical science is in Boron Neutron Capture Therapy (BNCT). Because of this, determination of neutron dose and flux is critical for the health maintaining of workers and patients exposed to this beam. The neutron radioisotope sources produce gamma rays in ...

Neutron Spallation Studies for an Accelerator Driven Subcritical Reactor

Nuclear power production can benefit from the development of more comprehensive alternatives for dealing with long-term radioactive waste. One such alternative is an accelerator-driven subcritical reactor (ADSR) which has been proposed for both energy production and for burning radioactive waste. Here we investigate the effects of the size of the ADSR spallation target on the total neutron yiel...

High-Yield D-T Neutron Generator

A high-yield D-T neutron generator has been developed for neutron interrogation in homeland security applications such as cargo screening. The generator has been designed as a sealed tube with a performance goal of producing 5·10 n/s over a long lifetime. The key generator components developed are a radio-frequency (RF) driven ion source and a beamloaded neutron production target that can handl...

Neutron Flux Underground Revisited

The neutron flux induced by radioactivity at the Gran Sasso underground laboratory is revisited. We have performed calculations and Monte Carlo simulations; the results offer an independent check to the available experimental data reported by different authors, which vary rather widely. This study gives detailed information on the expected spectrum and on the variability of the neutron flux due...
