3 MEV TO 90 MEV PROTON CYCLOTRON FOR NEUTRON BEAM PRODUCTION

摘要

Systems and methods for use of a proton beam or a negative hydrogen ion beam cyclotron for production of a flux of a neutron beam and its use in investigation of material analysis is provided. The methods, apparatuses and uses include positioning a target material for irradiation on a sample holder, focusing a proton ion beam or a negative hydrogen ion beam from the cyclotron to the target material; irradiating the target material to induce a proton-neutron reaction thereby producing a flux of a neutron beam; transmitting the flux of the neutron beam through a neutron spectrum modulator, focusing the flux of the neutron beam to a sample material thereby producing a radiation emission; and detecting the radiation emission using a detector.
