Abstract

The invention provides a continuous wave slow extraction synchronous accelerator. Multiple magnets used for synchronously accelerating heavy ions and / or protons comprise dipole magnets, quadrupole magnets and sextupole magnets, wherein the dipole magnets are used for turning of ion beam current, the quadrupole magnets are used for focusing of the ion beam current, and the sextupole magnets are used for matching of a phase space during slow extraction; each magnet is provided with at least one power unit electrically connected with the magnet, and each power unit comprises a voltage source andan energy storage capacitor; the voltage source is connected with the two ends of the energy storage capacitor and used for charging the energy storage capacitor; and multiple power units are connected in a series-parallel manner and then are electrically connected with the magnets and provide energy required in an ascent stage of a current waveform pulse for the magnets. By applying the continuous wave slow extraction synchronous accelerator provided by the invention, forward and reverse high pulsed power does not need to be extracted from a power grid, only forward constant power is needed,no interference is produced to the power grid, and power distribution capacity demand is reduced while beam current stability is improved.

Description

technical field

[0001] The invention relates to the field of synchrotrons, and further relates to a continuous wave synchrotron. Background technique

[0002] Because proton beams and heavy ion beams have the characteristics of inverted depth dose distribution, small side scatter, high relative biological effect and low oxygen increase ratio, etc., making proton and heavy ion cancer treatment become Today's international advanced and effective cancer radiation therapy; proton beams and heavy ions can also simulate the radiation environment in outer space, which is an effective method for aerospace single event effects and instrument radiation resistance detection; protons and heavy ions are still special materials A powerful means of irradiation, ion implantation and other applications; also used in nuclear physics, atomic physics experimental research.

[0003] The current mainstream heavy ion proton accelerators are divided into three categories, namely linear accelerator...
