Power Upgrade of J-parc Linac
The linac power upgrade program is now in progress, after a successful recovery from the earthquake disaster. The power upgrade includes an ion source, a RFQ, and a 400 MeV annular-ring coupled structure (ACS) linac. We started a full-scale development of a cesium-seeded RFdriven negative hydrogen ion source. The ion source extracted a beam current of more than 60 mA with a duty factor of 2.5 %...
متن کاملOperating Experience of the J-PARC Linac
The beam commissioning of the J-PARC linac started in November 2006 and 181 MeV acceleration was successfully achieved in January 2007. The linac has delivered beams to the 3 GeV Rapid Cycling Synchrotron for its commissioning, and then, the subsequent Main Ring Synchrotron and the neutron target commissioning. The linac uses a Cs-free LaB6-driven ion source and 20 units of 324 MHz klystrons. A...
متن کاملSingle Bunch Longitudinal Measurements of the Cornell Electron- Positron Storage Ring with the Superconducting RF Cavities
As part of the Phase III luminosity upgrade, the Cornell Electron-Positron Storage Ring (CESR) RF system has been upgraded from normal conducting (NRF) to superconducting (SRF) cavaties. The new superconducting cavities change the overall impedance of CESR and thus change the longitudinal bunch distribution. Measurements of the single bunch longitudinal distribution have been made using a strea...
متن کاملCold-model Tests of an Annular Coupled Structure for Upgrade of a J-parc Linac
An Annular Coupled Structure (ACS) has been developed for upgrade of a J-PARC (Japan Proton Accelerator Research Complex) linac from 180 MeV to 400 MeV. Although install area is prepared for the ACS cavities at an initial construction, it will be used as a beam-transport line temporarily. Aluminum and copper models were fabricated for RF properties confirmation based on an initial design, and f...
متن کاملHigh-energy hadron physics at J-PARC
The J-PARC facility is near completion and experiments will start in 2009 on nuclear and particle physics projects. In this article, the J-PARC facility is introduced, and possible projects are discussed in high-energy hadron physics by using the primary proton beam of 30−50 GeV. There are proposed experiments on charm-production and Drell-Yan processes as well as single spin asymmetries for in...
