Accelerator of muon has to have very large acceptance and very quick acceleration. Recent study shows that FFAGs (in particular non-scaling) are one of the most promising candidates for muon accelerators as building block for a neutrino factory. There are, however, some unresolved problems which should be studied in more detail. We will talk about mostly beam dynamics issues of the muon accelerators, not only FFAG, but other candidates such as linac and RLA and compare their performance.

THYAB02 Commissioning of the J-PARC Linac 2619
 
  • K. Hasegawa
 
  The J-PARC (Japan Proton Accelerator Research Complex?is a joint project between the Japan Atomic Energy Agency (JAEA) and the High Energy Accelerator Research Organization (KEK) to construct and operate the high-intensity proton accelerator facility. The J-PARC comprises a 400 MeV linac, a 3 GeV rapid-cycling synchrotron (RCS), a 50 GeV main ring synchrotron (MR) and experimental facilities. The energy of the linac is reduced to 181 MeV for the time being, and it will be increased to 400 MeV in the near future. The 3 MeV RFQ, which is a front end of the linac, has been beam commissioned since November 2006, and we will continue to work on the rest of the linac such as a 50 MeV DTL and a 181 MeV Separated-type DTL. The results and status of the J-PARC linac beam commissioning will be presented.
