Research Abstract

We have developed a new type of monoenergetic neutron source in the MeV region at Kyushu University Tandem Accelerator Laboratory(KUTL). The ^1H(^<13>C,n) reaction was chosen as a nuclear reaction to generate a monoenergetic neutron, which is based on the inverse(p,n) reaction kinematics and a neutron is expected to be emitted in the forward cone within a limited angle. A feasibility test experiment was performed using a 59.3MeV ^<13>C^<6+> beam incident on a hydrogen gas target. It was shown that kinematically collimated monoenergetic neutrons with 7.2MeV at 0 degree can be produced in the forward cone within 30 degree as expected by a neutron source simulation calculation. In addition, an optimization of a beam pulsing system was made for TOF experiments, and the time width of 3.8ns was achieved for a 4.0-MeVdeuteron beam. Also, high performance neutron spectrometers based on a recoil proton method were developed and their performance tests were made. An active radiator proton recoil counter telescope and a ray-trace-type proton recoil counter telescope were designed and fabricated. The performance of a fast neutron spectrometer with ^6Li capture gate was investigated for a MeV neutron monitor. As a result, it was demonstrated that these, neutron spectrometers are applicable to future experiments using the developed neutron source. Furthermore, a database of neutron cross sections for C,Mg,and Si up to 3GeV was developed and the neutron-induced soft error in semiconductor devices was studied in relation with future neutron beam applications.
