Research Abstract

Our goal is to obtain high intensity and high brightness secondary beams such as poin, muon, and neutrino. We call PRISM project after Phase Rotation Intense Secondary Meson Beam. There are two main subjects. One is development of superconducting magnet to capture pions. The other is a system of longitudinal phase rotation using a radio frequency cavity. The summary of the former development is the following. We made a test magnet of 10 T with 10 cm bore diameter. The magnet consists of one Nb3Sn coils and two NbTi one. We installed those two coils in a cryostat. A direct refrigerator was utilized in order to ease the maintenance under high radiation circumstance. The latter can be summarized as follows. New ferrite cores, which are called SY-25, were measured to obtain characteristic data, Under 10 MHz, shunt impedance is very high whereas it drops rapidly over 10 MHz. Those measurements strongly support the possible very high gradient cavity with the new ferrite.
