TUZAPA — Hadron Accelerators
Present Status of the J-PARC Accelerator
The Japan Proton Accelerator Research Complex
(J-PARC) is a joint project of High H. Kobayashi (KEK)
Energy Accelerator Research Organization
(KEK) and Japan Atomic Energy Agency (JAEA), which started on April 1, 2001. The J-PARC accelerator complex
is composed of a 400 MeV proton linac, a 3 GeV Rapid-Cycling Synchrotron (RCS), and a 50 GeV Proton
Synchrotron (MR). A 180-MeV beam ( in the first stage) accelerated by the linac is to be injected into the RCS, and
further accelerated there to 3 GeV. The RCS will operate at 25 Hz, and will provide the Materials and Life Science
Facility (MLF) with a 1-MW beam (600 kW during 180 MeV injection). There are two extraction sections in the MR:
fast extraction for neutrino experiment and slow extraction for the Hadron Facility. A linac beam with a peak current
of 30 mA and an energy of 19.7 MeV was successfully accelerated in Sep. 2004 using the first tank of the Drift Tube
Linac in KEK. Now three accelerators are under installation. The beam commissioning of the linac will start in this
December and those of the RCS and the MR will start in Sep. 2007 and May 2008, respectively. Status of installation
and plan for commissioning run will be presented.
Highlights from Commissioning HIRFL-CSR
The talk will cover the status and commissioning
results from the Cooling Storage Ring
and Heavy Ion Research Facility in Lanzhou.
