Description
This paper details the development of Thailand’s first prototype in-vacuum wiggler (IVW). The project initiated with 3D magnetic field simulations using the RADIA package to define the optimal magnetic configuration. To verify their magnetic properties and ensure field quality, individual magnet blocks are characterized using a Helmholtz coil system operated via in-house developed control software. The magnet arrays are assembled onto an in-vacuum girder utilizing a custom workstation and specialized keeper tools to maintain strict mechanical tolerances and ensure safety against strong magnetic forces. Optical alignment using a leveling camera verifies girder planarity and gap consistency prior to final metrology. Furthermore, this work details a custom-built Hall probe measurement bench—also driven by newly developed control and data acquisition software—which is employed for the inaugural field mapping of the assembled IVW. A preliminary comparison between the experimental field data and RADIA simulations, prior to the application of shimming or magic finger end-field corrections, is presented. This study establishes a critical technical framework for future high-performance ID development in Thailand.
