Beam Commissioning of a Multi-purpose Compact Ion Synchrotron
نویسندگان
چکیده
W-MAST (Wakasa-wan Energy Research Center Multipurpose Accelerator with Synchrotron and Tandem) consists of a tandem accelerator with 5MV terminal voltage and a compact ion synchrotron. The beam commissioning was started at the beginning of 1999 and was successfully accomplished in March 2000. A proton beam of 10MeV was injected from the tandem accelerator and accelerated by the ion synchrotron to 200MeV during 0.6s. In order to reduce the space charge induced tune spread, the second order harmonic component was superposed onto the accelerating radio frequency field with an untuned accelerating cavity having FINEMET cores. Betatron tune during the acceleration was measured and controlled to improve the acceleration efficiency.

Rf Accelerating System for a Compact Ion Synchrotron
We have developed an RF accelerating system for a compact ion synchrotron. The RF cavity is an untuned type loaded with FINEMET cores, which have high complex permeability, high saturation flux density, and high Curie temperature properties. A new power feeding method, “multi-feed coupling,” was developed to match the cavity impedance with output impedance of a solidstate RF amplifier. We have ...

MedAustron is the Austrian center for hadron therapy and non-clinical research. The accelerator design is based on the PIMMS study [1] and features proton beams of up to 800 MeV and carbon ion beams of up to 400 MeV/u. The accelerator is currently being installed and the beam commissioning has started early 2013. The injector comprising three ECR sources, an RFQ and an IH-mode structure has alr...
متن کاملCommissioning and Performance of the HIMAC Medical Accelerator
Heavy ions show the excellent dose concentration especially at a position located deep in a human body. This character of heavy ions are well suited for the medical treatment of the cancer. A heavy ion synchrotron complex, HIMAC, has been constructed at NIRS for this purpose. The HIMAC accelerator consists of an injector linac, a couple of synchrotron rings, long and complicated beam transport ...
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 کاملCompact Medical Cyclotrons and their use for Radioisotope Production and Multi-disciplinary Research
Compact medical cyclotrons are conceived for radioisotope production in a hospital-based environment. Their design in terms of field shape, stability and radio-frequency (RF) is aimed at obtaining high intensity (>150 μA) beams at kinetic energies of the order of 20 MeV. To guarantee high performances, an optimization procedure during the commissioning phase is crucial as well as a regular prev...
