    摘要： The linac (700) includes an electron gun for generating an electron beam, and a plurality of accelerating cavities (720a- g)which accelerates the electron beam by applying electromagnetic fields generated by a microwave source. At least two adjacent accelerating cavities of the plurality of accelerating cavities are coupled together by at least one coupling iris (718a). The electromagnetic fields resonate through the plurality of accelerating cavities, and the operating frequency of the electromagnetic fields is selected so that the linear accelerator is operating at a pi-mode or a mode close to the pi- mode.

    摘要： System for ion acceleration for medical purposes comprising a conventional or superconducting cyclotron, a radiofrequency linear accelerator (Linac), a Medium Energy Beam Transport line (MEBT) connected, at the low energy side, to the exit of the cyclotron, and at the other side, to the entrance of the linear radiofrequency accelerator, as well as a High Energy Beam Transport line (HEBT) connected at high energy side to the radiofrequency linear accelerator exit and at the other end, to a system for the dose distribution to the patient. The high frequency of operation of the Linac allows for a reduced consumption and a remarkable compactness facilitating its installation in hospital structures. The use of a modular LINAC allows varying in active way the energy and the current of the therapeutic beam, having a small emittance and a time structure adapted to the dose distribution based on the technique known as the 'spot scanning'.

    摘要： A phase switch (energy switch) comprising a three-cavity system (an end-coupled cavity + a side-passed accelerate cavity + an end-coupled cavity) and a separate single couple cavity is disclosed. The phase shift between the adjacent accelerate cavities is π when the three-cavities system is disordered (state '0'); and a microwave pass through the three-cavities system to the adjacent accelerate cavities, the phase between the adjacent accelerate cavities is change to 2π (or 0) when the single couple cavity is disordered (state '1'). When the state 0 changes to state 1, the field phase in the structure behind the system is changed to π, thereby to switch the phase. In the two states, the entire structure operates in π/2 mode, that is very stable. That is very important for the medical accelerator. The detaining components have been moved outside the cavity when the single couple cavity or the three-cavity system is in the operate state, without warring about high frequency breakdown. By changing couple between the two end-coupled cavities in the three-cavity system and the adjacent accelerate cavities and between the cavities in the system, the relative field-strength in the acceleration section besides the switching is changed while the phase reverses. It can be used for 6Mev accelerator middle-energy or high-energy accelerator.

    摘要： @ A compact, small diameter, standing-wave linear accelerator structure suitable for industrial and medical applications is disclosed. The novel structure utilizes a new type of coupling cavity for Pi/2 mode, standing-wave operation. The coupling cavity fits into the webs between the accelerating cavities substantially within the diameter of the accelerating cavities. This is made possible by keeping the center section of the cavity thin to concentrate the electric field vector at the center of a section of the cavity and by enlarging the ends of a section of the coupling cavity to accommodate the magnetic field vector. This structure offers a significant reduction in overall diameter over the side-coupled, annular ring, and existing coaxial coupled structures, while maintaining a high shunt impedance and large nearest neighbor coupling (high group velocity). A prototype 4 MeV, 36 cm long, S-band accelerator incorporating the new structure has been built and tested.
