Magnetic field measurement of pulsed magnets at KEK electron/positron injector linac

  • 1. High Energy Accelerator Research Organization (KEK), Tsukuba, Ibaraki (Japan)

Description

Pulsed magnets at the KEK Electron/Positron Injector Linac have been installed for optimizing beams which are transported pulse-by-pulse at 50 Hz to achieve simultaneously inject beams with different specifications into four independent downstream rings. This paper reports the result of magnetic field measurements of pulsed magnets by driving an actual power source which supplies a pulsed shape close to a trapezoid with a rise time and a fall time of 2 ms, a flattop of 1 ms with a current of 300 A or 600 A.

Abstract (Japanese)

KEK電子陽電子入射器(Linac)は、下流の独立した4つのリングへ異なる仕様のビームを同時入射するために、ビーム輸送系にパルス電磁石を導入している。パルス電磁石の励磁電流は、各ビームモードのオプティクス仕様に合わせた磁場強度にする必要があるため、パルス電源の生成するパルス波形も特殊である。ここでは、KEK電子陽電子入射器のパルス電磁石系の磁場測定について報告する。(著者)
