Description
J-PARC is going to achieve its designed proton beam power of 0.75 MW at 30 GeV for neutrino physics and 1 MW at 3 GeV for material and life sciences in several years. Recently, discussions of heavy ion acceleration as the future J-PARC project have been held among nuclear physicists and accelerator scientists.
The main goals of the program are to explore the QCD phase diagram at high baryon density with the heaviest ions such as uranium at the beam energies of around 10 AGeV. We are planning to focus on the electron and muon measurements and rare probe search such as multi-strangeness and charmed hadrons by taking advantage of the world's highest beam power available at J-PARC, in addition to identified hadron measurements in large acceptance.
A heavy-ion acceleration scheme has been considered with a new heavy-ion linac and a new booster ring, which accelerate and inject heavy-ion beams into the existing 3-GeV Rapid-Cycling Synchrotron, and the 30-GeV Main Ring synchrotron.
We present the overview of the heavy-ion program and accelerator design, as well as physics goals and conceptual design of the heavy-ion experiments.
