	Beam test of the direct plasma injection scheme (DPIS) is carried out successfully for the first time in China, by setting up a comprehensive test and research platform of RFQ and laser ion source. The C⁶⁺ beam is accelerated successfully, and the peak beam current reaches more than 6mA which is measured by a Faraday cup of unique structure. The RF power coupled into the RFQ cavity is also examined, and results reveal that it is the RF power of about 195kW that can produce the peak beam current.

We present a design of the ion Rapid Cycling Medical Synchrotron (iRCMS) for carbon/proton cancer therapy facility. The facility design, produced at Brookhaven National Accelerator (BNL) at the Collider Accelerator Division (CAD) for the BEST Medical International, Inc., will be able to treat the cancer patients with carbon, lighter ions and protons. The low energy part accelerates ions and protons to the kinetic energy of 8 MeV. It consists of two ion sources (one of fully stripped carbon ions and one for protons), a Radio-Frequency Quadrupole (RFQ) and linac. The 8 GeV beam is injected into a fast cycling synchrotron (iRCMS). The lattice design is a racetrack, with zero dispersion two parallel straight sections. There are 24 combined function magnets in the two arcs with a radius of ~5.6 meters with maximum magnetic field of less than 1.3 T. The acceleration is performed in 30 Hz up to the required energy for the cancer tumor treatment assuming the spot scanning technique. The maximum energy for carbon ions is 400 MeV. Ions are extracted in a single turn and fed to different beam lines for patient treatment.

We present a design of the ion Rapid Cycling Medical Synchrotron (iRCMS) for carbon/proton cancer therapy facility. The facility design, produced at Brookhaven National Accelerator (BNL) at the Collider Accelerator Division (CAD) for the BEST Medical International, Inc., will be able to treat the cancer patients with carbon, lighter ions and protons. The low energy part accelerates ions and protons to the kinetic energy of 8 MeV. It consists of two ion sources (one of fully stripped carbon ions and one for protons), a Radio-Frequency Quadrupole (RFQ) and linac. The 8 GeV beam is injected into a fast cycling synchrotron (iRCMS). The lattice design is a racetrack, with zero dispersion two parallel straight sections.
