  The Taiwan photon source (TPS) transfer line from the linac to the booster (LTB) is made of 1 bending magnet, 11 quadrupoles and the booster to the storage ring (BTS) is include of 2 bending magnets, 7 quadrupoles. LTB bending magnet is provided for 11 degrees defection from the linac to the booster and 31 degrees from the linac to the beam dumper with two operating currents. The BTS quadrupoles are included four 0.3m and three 0.4m magnets which cross sections are the same with booster quadrupole give different integral quadrupole field strengths and cooling systems are redesign from 2 circuits to 4. The magnetic fields were simulated with Opera 2D and 3D; optimum processes are discussed. All of the magnets have been constructed by Danfysik, scanditronix and Gongin. This paper discusses the features, the design concept and the results of field measurements of these transfer line magnets.

  The Taiwan Photon Source (TPS) is a 3-GeV synchrotron radiation facility operated in top-up injection mode. The booster ring of TPS shares the same tunnel, concentric with the storage ring. The lattice of the booster is a 24-cell DBA of circumference 496.8 m. The energy of the electron beam is ramped from 150 MeV to 3 GeV at repetition rate 3 Hz in the booster ring. The trajectory of the electron beam is controlled with complicated combined-function magnets including combined dipole magnet, combined quadrupole magnet, pure quadrupole magnet, sextupole magnet and corrector magnet. The measurement and performance of these magnets are discussed in this letter.
