Substance Detection using mono-energetic neutrons
ثبت نشده
چکیده
A method and apparatus for determining the nitrogen and oxygen composition of an arbitrary object in a non-evasive manner is presented. The object of interest is irradiated with fast monoenergetic neutron beams and the resulting pulse height spectra of scattered neutrons are measured using a SP2 spherical counter and unfolded to calculate the cross section of the object. The cross section is then compared to the well-known resonant cross section of nitrogen and oxygen. The potential of the method for making a bomb-detecting device is investigated.

Dose equivalent from 500 MeV neutrons
Neutrons constitute a major component in the radiation fi eld outside the shielding of particle accelerators. Consequently appropriate neutron dose meters are needed to survey the radiation levels. A thermo-luminescence based neutron dosemeter is used at the UNILAC as well as at the SIS. It has been modifi ed to improve the response for high energetic neutrons (extended range). We report on a t...
متن کاملPhysics of Solar Neutron Production : Questionable Detection of Neutrons from the 2007 December 31 Flare
Spacecraft observations in the inner heliosphere offer the first opportunity to measure 1–10 MeV solar neutrons. We discuss the physics of low-energy neutron production in solar flares and show that, even at interacting-particle energies of 2 MeV nucleon, neutrons with energies >10 MeV are produced. On the other hand, a significant fraction of 1–10 MeV neutrons result from interactions of >10 M...
متن کاملEvaluation of the accuracy of mono-energetic electron and beta-emitting isotope dose-point kernels using particle and heavy ion transport code system: PHITS.
We assessed the accuracy of mono-energetic electron and beta-emitting isotope dose-point kernels (DPKs) calculated using the particle and heavy ion transport code system (PHITS) for patient-specific dosimetry in targeted radionuclide treatment (TRT) and compared our data with published data. All mono-energetic and beta-emitting isotope DPKs calculated using PHITS, both in water and compact bone...

In organic scintillators, the energy distribution of gamma rays and neutrons is indirectly measured by the pulse height distribution of light output produced through gamma ray and neutron reactions in the detectors. Accurate estimate of the interaction of gamma and neutrons in the detector and produce charged secondary particles and subsequent scintillation light produced in the calculation of ...

Background : Performing successful BNCT experiments needs a suitable neutron source. Important factors of the neutron beam are flux and energy that are very important in the selection of neutron source. In most centers that use this method for treatment, reactor is a neutron source, which according to characteristics of the reactor appropriated neutrons are very high. High cost of constructin...
