Description

We present a hybrid permanent magnet-based adjustable phase undulator, featuring a period length of 17.2 mm, a gap of 8.5 mm, and a total length of 2.4 m. This planar polarized undulator adjusts field intensity through longitudinal jaw movement, with mechanically linked magnet arrays ensuring smooth motion. Building on previous work, this report focuses on newly developed tuning techniques for trajectory and phase error correction. Our engineering experience demonstrates the effectiveness of these methods in optimizing undulator performance.
