Development of the nonlinear in-vacuum kicker at Taiwan photon source
Year: 2025
Type: article
Abstract: A nonlinear in-vacuum kicker (NIK) was developed to facilitate beam injection into the Taiwan Photon Source (TPS) storage ring. The system consists of a titanium vacuum chamber that encloses a ceramic support structure, precisely aligning eight copper kicker coils to generate the desired nonlinear magnetic field profile. Experimental measurements show that the profile of the first magnetic integral closely aligns with simulation result. To reduce heating from image currents and minimize magnetic field attenuation, a 5 μm-thick titanium coating was applied to the ceramic surface. Outgassing rate measurements and pressure readings after bake-out and pump activation confirm that the nonlinear in-vacuum kicker meets the ultra-high vacuum (UHV) requirements for TPS storage ring operation.
