	C.Y. Liao, Y.-S. Cheng, K.T. Hsu, K.H. Hu, C.-C. Kuo, H.-J. Tsai, C.Y. Wu NSRRC, Hsinchu, Taiwan
	Taiwan Photon Source (TPS) is a third-generation 3-GeV synchrotron light facility, located in National Synchrotron Radiation Research Center (NSRRC) at Hsinchu Science Park. After overcoming many challenges, the storage beam current attained 520 mA in 2015 December. The synchrotron light monitors, including X-ray and visible light, are important diagnostic tools to characterize the various machine conditions. The booster beam dynamics during ramping and the beam properties of the storage ring were studied with synchrotron light. The results of measurements are presented in this report.

MOPOR017	First Year Performance of the TPS Booster Ring	634
	H.-J. Tsai, P.J. Chou, K.T. Hsu, K.H. Hu, C.-C. Kuo, C.Y. Liao, Y.-C. Liu, G.-H. Luo, F.H. Tseng NSRRC, Hsinchu, Taiwan
	The Taiwan Photon Source (TPS) is a 3-GeV low- emittance light source of circumference 518.4 m. The booster ring is in the same tunnel with the storage ring; its circumference at 496.8 m makes it the largest booster ring in operation in existing light sources. Since the successful commissioning at the end of 2014, the TPS booster ring has been optimized in performance for routine operation. In this paper, we present the system upgrade and the improvement of the ramping procedure to increase the capture and ramping efficiency of the beam charge, the characterization of the optics, etc.

THPMB049	Optics Calibration During Commissioning of the Taiwan Photon Source	3357
	F.H. Tseng, C.H. Chen, J.Y. Chen, M.-S. Chiu, C.-C. Kuo, Y.-C. Liu, H.-J. Tsai NSRRC, Hsinchu, Taiwan
	The Taiwan Photon Source is a 3-GeV low emittance synchrotron light machine with circumference of 518.4m. The lattice is with 24-cell DBA structure and emittance is 1.6 nm-rad. During the commissioning in the past year, we employed MATLAB-based high level applications to calibrate the optical functions in three different operation lattice modes. In particular, we used LOCO (Linear Optics from Closed Orbit) to restore the machine optical functions and reduce emittance coupling ratio. The beam-based alignment (BBA) measurements as well as BPM and corrector errors were identified.

	The Taiwan Photon Source (TPS) is a low-emittance 3-GeV light source at Natioal Synchrotron Radiation Research Center, next to the Taiwan Light source (1.5 GeV). On March 26, 2015, the TPS storage ring with two 5-cell PETRA cavities has successfully operated in 100 mA in top-up mode without the installation of insertion devices (IDs). To reach the design goal of 500 mA, the machine was shut down for 5 months to replace PETRA cavitites with superconducting RF (SRF) cavities and to install 10 IDs: 7 in-vacuum undulators (IU) and 3 elliptically polarized undulators (EPU). The commissioning of TPS storage ring with SRF cavities and IDs began in Sep. 2015. In this paper, we present our results and proceedures of ID commissioning.
