A concept of coupled cyclotrons for acceleration of carbon ions (charge 6+) to 400 MeV/nucleon by a separated sector cyclotron consisting of six sector magnets with superconducting coils is proposed. Injection to the machine will be provided by a compact 70 MeV/nucleon cyclotron. The accelerator complex is intended for setting up a radiation therapy facility employing carbon ions. The advantages of the dual cyclotron design are typical of cyclotron-based solutions. The first design studies of the sector magnet of the main cyclotron (magnetic field increases from 4.2 T to 6.5 T, RF frequency 73.56 MHz, RF mode 6) show that it is feasible with acceptable beam dynamics. The accelerator has a relatively compact size (outer diameter of 8 m) and can be an alternative to synchrotrons.

A 12.5 MeV, 25 μA, proton compact superconducting cyclotron for medical isotope production has been produced. The machine is initially aimed at producing 13N ammonia for Positron Emission Tomography (PET) cardiology applications. With an ultra-compact size and cost-effective price point, this system offers clinicians unprecedented access to the preferred radiopharmaceutical isotope for cardiac PET imaging. A systems approach that carefully balanced the subsystem requirements coupled to precise beam dynamics calculations was followed. The system is designed to irradiate a liquid target internal to the cyclotron and to minimize the need for radiation shielding. The overall engineering, construction, commissioning, and experience at the first customer site will be described here.
