LINEAR ACCELERATOR

摘要

2113069 9301645 PCTABS00019 A linear accelerator (2) has at least one longitudinal stator section (4) that defines a linear path of movement and that comprises several stator coils (8, 10, 12, 14), as well as a rotor (30) with several rotor coils (34, 36, 38, 40) that can be accelerated along the path of movement. The stator is designed as a tubular body (6) upon the inner wall of which project coil carriers with coil conductors that are mutually offset by 90 ·. The thus formed cavities (16, 18, 20, 22) are engaged by the rotor coils (34, 36, 38, 40) that comprise each an electrically non-conductive carrier on the sides on which are arranged meandering coil conductors. The design and arrangement of the rotor coils (34, 36, 38, 40) and stator coils (8, 10, 12, 14) allow a circular magnetic field to be generated, with the result that the rotor (30) is axially accelerated. The rotor (30) is supplied with current by conductor rails (54, 56, 58, 60), by a cable entrained with the rotor (30) and/or by charge accumulation in the coils before acceleration begins.
