Outline of Final Research Achievements

The intensity monitor for the secondary particles is developed to enhance the sensitivity of the search for asymmetry between matter and anti-matter (CP violation) in the neutrino oscillation experiment by measuring the difference between the neutrino-beam and the anti-neutrino beam that are produced using high intensity proton accelerator, J-PARC. Because the secondary particle monitor is required to measure the flux of secondary particles that are the parent-particles of neutrinos under the high radiation environment, the radiation-hardness current transformer (CT) is developed. The prototype of the CT is produced, and it is confirmed that the prototype CT has the basic performance to measures the expected current produced by the secondary particles at the J-PARC neutrino beam-line.
