Abstract
Robinson wiggler is a special insertion device that can be used to decrease natural emittance of the Taiwan Photon Source (TPS) storage ring. This Robinson wiggler can change damping partition number and then affect the emittance. This study will evaluate practicability of reducing the emittance of TPS storage ring by Multiperiod Robinson Wiggler (MRW) in the 7 m long straight section. One period of the traditional Robinson Wiggler include four poles with different field polarity. In the same length, the multi-period Robinson Wiggler has been over four poles in one set of Robinson Wiggler that is different from the traditional Robinson wiggler. Due to the traditional Robinson wiggler cannot be effective to improve emittance in TPS storage ring (the efficiency is only 7% with 6 straight sections). So we adopt to use multi-period Robinson Wiggler, the efficiency can be up to 30% with 6 straight sections, and the linear matching result is better than traditional Robinson Wiggler.
