FIELD: physics.
SUBSTANCE: particles are accelerated in a magnetic field increasing over time, in which the average value of magnetic flux density inside the equilibrium orbit Bav is much less than the magnetic flux density at the equilibrium orbit. B0 ("Bav<<B0"), In order to keep the radius of the equlibrium orbit constant during acceleration, special relationships between amplitude-time characteristics of magnetic flux density on the orbit and the induced acceleration voltage are satisfied. In order to realise strong focusing, magnetic field with a large alternating gradient is formed on the orbit. The absence of resonant accelerating systems and synchronisation of accelerating pulses with pulses of the time-of-flight beam system enables to accelerate particles in a wide range of particle energy (velocity) with constant equilibrium radius during acceleration.
EFFECT: reduced weight and size of the accelerator with a wide range of ion velocity during acceleration, reduced cost of the accelerator and wide range for regulating energy of the accelerated ions, which is necessary when using accelerators in medicine and scientific research.
