WEPSB29	The Induction Synchrotron with a Constant Magnetic Field	dipole, focusing, acceleration, betatron	223
	G. Dolbilov JINR, Dubna, Moscow Region, Russia
	In this report possibility of cyclic acceleration of the charged particles in constant in time a magnetic field is discussed. The closed orbit of particles is formed by a set of magnetic dipoles. In each section of dipoles the radial dispersion of trajectories of a beam depends on the azimuthal length of a dipole and has the small size (on the order of several centimeters). As the dipole section has radial focusing and vertical defocusing, using quadrupole lenses between dipole sections it is possible to organize alternating-sing focusing on all perimeter of the accelerator. Particles are accelerated by electric field of the induction sections which powering up is made at bunch approach. The inductor of sections are remagnetized in the range of time between a beam bunches. Stability of longitudinal oscillations is defined by a form of a table of accelerating induction pulses. Such accelerator is able to afford to expand the range of parameters of accelerated particles on their charge and atomic weight as doesn't demand compliance of a resonance of HF-system to the frequency of the circular frequency of accelerated particles.

	G. Dolbilov JINR, Dubna, Moscow Region, Russia
	The electron accelerator with energy <10 MEV uses a rectangular pulse of the accelerating induction voltage and a trapezoidal pulse of a leading magnetic field. For preservation of radius of an equilibrium orbit to constants special ratios between amplitude-time characteristics of a magnetic induction and the accelerating voltage of inductors are carried out. The accelerator contains alternating-sign focusing in dipole magnets and rectilinear accelerator parts. Total cross-section of inductors of accelerating section is equal to S=WL/Bc, (W-energy of electrons, L-perimeter of an orbit, B<2Bs, Bs-индукция of saturation of inductors, c - velocity of light)
