Fusion neutron detector calibration using a table-top laser generated plasma neutron source
نویسندگان
چکیده
Using a high intensity, femtosecond laser driven neutron source, a high-sensitivity neutron detector was calibrated. This detector is designed for observing fusion neutrons at the Z accelerator in Sandia National Laboratories. Nuclear fusion from laser driven deuterium cluster explosions was used to generate a clean source of nearly monoenergetic 2.45MeV neutrons at a well-defined time. This source can run at 10Hz and was used to build up a clean pulse-height spectrum on scintillating neutron detectors giving a very accurate calibration for neutron yields at 2.45MeV. r 2004 Elsevier B.V.

The most important part of neutron therapy treatment (NCT1) is to achieve a beam of neutrons with suitable energy and intensity, as well as the least pollution and damage. In this study, in order to correct the neutron spectrum from D-D fusion and its use in neutron therapy, a set of different materials which are called the Beam Shaping Assembly (BSA) was placed in the direction of energy 2.45 ...
متن کاملCalibration of time of flight detectors using laser-driven neutron source.
Calibration of three scintillators (EJ232Q, BC422Q, and EJ410) in a time-of-flight arrangement using a laser drive-neutron source is presented. The three plastic scintillator detectors were calibrated with gamma insensitive bubble detector spectrometers, which were absolutely calibrated over a wide range of neutron energies ranging from sub-MeV to 20 MeV. A typical set of data obtained simultan...

Introduction: Environmental and occupational human exposure from neutron source can lead to the serious biologic effects. The aim of this study is to evaluate the cancer incidence risk for various human organs at different neutron dose levels due to exposure from an Americium-241/Beryllium (Am-241/Be), a standard neutron source for calibration purposes. Material and Methods: We measured ambient...
متن کاملNeutron Detection with High Bandwidth and High Dynamic Range
A neutron diagnostic for inertial confinement fusion (ICF) experiments was designed and fabricated that is suitable for both the OMEGA and National Ignition Facility (NIF) laser systems. The diagnostic measures the spectrum of fusion neutrons that are generated at peak compression. The neutrons are downshifted, or lose energy, as they escape depending on the areal density (ρr) of the imploded t...
