Activation studies were performed in JET with new in-vessel activation monitors. Though primarily dedicated to R&D in the challenging issue of lost diagnostics for ITER, which is being addressed at JET with several techniques, these monitors provide for both neutron and charged particle fluences. A set of samples with different orientation with respect to the magnetic field is transported insid...

The slow neutron capture process produces heavy elements in different stellar sites at temperatures. Neutron cross sections for temperatures between k B T = 5 keV and 100 are crucial a quantitative understanding of the s-process abundance distribution. Over last decade activation measurements were performed Goethe University Frankfurt to study temperature 25 keV. We developed new method measure 6

Archeological artifacts can be analyzed after neutron irradiation at the pulsed ISIS and muon source, UK, using a newly installed high purity germanium gamma ray spectrometer to perform activation analysis. In this work, details of measurement methods data analysis are presented. particular, it is explained how Monte Carlo calculations necessary evaluate detection efficiency, taking into accoun...

Prompt gamma-ray neutron activation analysis (PGNAA) is now a proven method for the identification of chemical warfare agents and explosives in military projectiles and storage containers. Idaho National Laboratory is developing a next-generation PGNAA instrument based on the new Ortec Detective mechanically-cooled HPGe detector and a neutron generator. In this paper we review PGNAA analysis of...

background: boron neutron capture therapy (bnct) is a very promising treatment for patients suffering gliobastoma multiforme, an aggressive type of brain cancer, where conventional radiation therapies fail. thermal neutrons are suitable for the direct treatment of cancers which are located at near-tissue-surface deep-seated tumors need harder, epithermal neutron energy spectra. materials and me...

Abstract Neutron spectrum unfolding using activation foils is currently the primary technique planned for measuring neutron energy at first wall of power-generating fusion reactors. Room improvement in effectiveness current foil selection was identified, and a program produced to select procedurally order maximise accuracy procedure. Using Kullback–Leibler Divergence quantify accuracy, unfolded...

Background: Several landmine detection methods, based on nuclear techniques, have been suggested during the recent years. Neutron energy moderation, neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are nuclear-based methods used for landmine detection. The aim of this study is to use backscattered neutron for landmine detection. Materials ...
