Latest Patents
One of Plastun's key inventions is the Compac carbon ion LINAC. This patent provides a method for accelerating protons and carbon ions up to 450 MeV/u in a very compact linac. The method involves subjecting the particles to a radio frequency quadrupole field to accelerate them to at least 3 MeV/u, followed by a drift tube linac (DTL) to an energy of 20 MeV/u. The process continues with a coupled DTL to 45 MeV/u and culminates in a high-gradient section made of CCL-type standing wave cavities or negative harmonic traveling wave cavities operating at S-band frequencies. This design is capable of delivering voltage gradients of 40 to 60 MV/m.
The compactness and power efficiency of the linac are achieved by utilizing high-gradient structures in the S-band frequencies for lower energy particles than ever before. The low intensity required for hadron therapy allows the use of small-aperture S-band structures and operation at very high gradients compared to high-intensity machines used for research. The system operates with very short sub-microsecond pulses at repetition rates up to 400 Hz, enabling fast and flexible beam energy and intensity tuning that existing hadron therapy machines do not provide. The designed linac can accelerate ions as heavy as neon to the full 450 MeV/u energy, allowing for rapid beam switching if different ion sources are installed in the front-end of the linac.
