utilization of photodisintegration reaction of deuterium, 2h(?,n)1h, is a precise technique for determining the percentage of 2h in tritiated and natural water. the 23na(n,?)24na reaction is a suitable ?-source for producing the 2h(?,n)1h reaction. tehran research reactor was used as a neutron source for producing 24na isotopes. the bf3 detectors were used to detect the neutron emission of h2 c...

The possibility to use the ultrashort ion bunches produced by circularly polarized laser pulses to drive a source of fusion neutrons with sub-optical cycle duration is discussed. A two-side irradiation of a deuterated thin foil target produces two countermoving ion bunches, whose collision produces an ultrashort neutron burst. Using particle-in-cell simulations and analytical modeling, it is ev...

background: the poly-allyl diglycol carbonate (padc) detector is of particular interest for development of a fast neutron dosimeter. fast neutrons interact with the constituents of the cr-39 detector and produce h, c and o recoils, as well as (n, α) reaction. these neutron- induced charged particles contribute towards the response of cr-39 detectors. material and methods: electrochemical etchin...

Fission chambers were first made fifty years ago for neutron detection. At the moment, the French Atomic Energy Commission (CEA-Cadarache) is developing a sub-miniature fission chamber technology with a diameter of 1.5 mm working in the current mode [1]. To be able to measure intense fluxes, it is necessary to adjust the chamber geometry and the gas pressure before testing it under real neutron...

The International Atomic Energy Agency (IAEA) requires that all test and research reactors operating on Higher Enriched Uranium (HEU) should be converted to Low (LEU) for safety security purposes. Nigeria having a Miniature Neutron Source Reactor (MNSR) has been long interested in fuel technological not just develop the area but also meet with resolution nuclear treaty set out by global regulat...
