การออกแบบและสร้างขดลวดแม่เหล็กหกขั้ว สำหรับวงกักเก็บอิเล็กตรอนพลังงาน 1.2 GeV ของเครื่องกำเนิดแสงซินโครตรอน - ประเทศไทย

Abstract

This article presents the winding design and construction for a sextupole magnet of the synchrotron light source storage ring on Thailand (Siam Photon Source) upgraded from 1.0 GeV to 1.2 GeV to produce an x-ray emission. It is designed to absorb magnetomotive force of 2,200 ratings while maintaining the coil temperature below 60 °C. The design utilizes various software packages: Accelerator Toolbox was used for sextupole excitation current calculation, POISSON and RADIA for 2D and 3D magnetic field calculations, and COSMOSWorks^TM for coil temperature calculation. The calculated and measured results are compared. The magnetic field measurement was carried out by the automatic three-axis magnetic field measurement system developed in-house. The new winding functions well according to the required ratings.
