Taiwan Photon Source (TPS) project is undergoing booster commissioning. Few issues have been discovered and fixed. Since the booster aperture is relatively small and insufficient number of magnets, extreme precise control of booster chamber alignment and its magnetic quality is relatively important. In this paper, we present how we uninstall booster chamber, demagnetize them and put them back within 3 weeks. The result is very promising and the lowest booster chamber permeability in the world is built.
