| Research Abstract |
We have promoted a development of high intensity pulsed muon beam with high purity at J-PARC, where user operation has been started in 2008. This has contributed to opening up a new research area in elementary particle physics. In this research there should be no beam particle leakage in between consecutive beam pulses. In order to address this issue we developed a new method to form a beam pulse and a method to diagnose the produced beam.
