| Abstract |
Robinson wiggler is a special insertion device that can be used to decrease natural emittance of the Taiwan Photon Source (TPS) storage ring. There are four poles in one set of Robinson Wiggler and each pole has combined with dipole and quadrupole field strength. The dipole field strength multiply quardupole field strength in each pole should be negative. 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 muti-period Robinson wiggler and will be installed 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 mult-period Robinson Wiggler have many period in one set of Robinson Wiggler that is different from the traditional Robinson wiggler. Due to the traditional Robinson wiggler can not be effective to improve emittance in TPS storage ring (the efficiency is only 7%). So we adopt to use muti-period Robinson wiggler, the efficiency can be up to 37%, and the linear matching result is better than one period Robinson Wiggler.
