Power Upgrade of J-parc Linac

چکیده

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 %, satisfying the requirement of the program. A new RFQ for 50 mA acceleration is under construction, on the basis of a RFQ fabrication process, which was previously built as a backup for the present RFQ. Mass production of the ACS modules has been completed.

Cold-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...

Prospect of Heavy - ion Collision Experiments at J - PARC

In order to explore phase structures in high-baryon density regime of the QCD phase diagram and study dense quark/hadronic matter which may exist in the core of neutron stars, we proposed a heavy-ion program at J-PARC (J-PARC-HI). In heavy-ion collisions at J-PARC (1-19 AGeV/c), the maximum baryon density reaches 5-10 times the normal nuclear density. We designed heavy-ion acceleration scheme a...

Operating 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...

Measurement of Resonant Space Charge Effects in the J-parc Linac

Traditionally, high intensity linac designs follow the “equipartitioning condition”, a strict control of the transverse and longitudinal tune ratios throughout the linac that ensures space-charge driven emittance exchange between the longitudinal and transverse planes is minimised. However, equipartitioning imposes strict rules on the linac design, thus limiting the design options and increasin...

A New 180 MeV H Linac for Upgrades of ISIS

Several options have been studied to raise the beam power of the ISIS spallation neutron source to a level of 1 MW with the possibility of going to 4-5 MW in the longer term [1]. All scenarios can operate in 2 modes, where the beam power is either delivered to a spallation target or, alternatively, to a target suitable to produce muons via pion decay for a neutrino factory. A more recent upgrad...
