TUP049 | Vane Machining by the Ball-end-mill for the New RFQ in the J-PARC Linac | rfq, linac, cavity, gun | 518 |
|

The J-PARC RFQ (length 3.1m, 4-vane type, 324 MHz) accelerates a negative hydrogen beam from 0.05MeV to 3MeV toward the following DTL. We started the preparation of a new RFQ as a backup machine. The new cavity is divided by three unit tanks in the longitudinal direction. The unit tank consists of two major vanes and two minor vanes. A numerical controlled machining with a conventional ball-end-mill has been chosen for the vane modulation cutting instead of the wheel shape cutter. In this presentation we will report the machining procedure, the results of the vane machining, RF properties, and some topics during the fabrication. |

FR202 | Muon Colliders and Neutrino Factories | collider, cavity, acceleration, electron | 1048 |

Over the last decade there has been significant progress in developing the concepts and technologies needed to produce, capture and accelerate O(1021) muons/year. This development prepares the way for a new type of neutrino source (Neutrino Factory) and a new type of very high energy lepton-antilepton collider (Muon Collider). A review is given of the motivation, design and R&D for Neutrino Factories and Muon Colliders. |
