	The Taiwan Photon Source (TPS) is a 3-GeV third-generation synchrotron light source located in Hsinchu, Taiwan. After ground breaking on February 7, 2010 and five years of construction and hardware developments, commissioning of the beam began on December 12, 2014. The booster ring reached the design energy of 3 GeV on December 16. Beam transferred to the storage ring and first accumulation at 3 GeV produced the first synchrotron light on December 31. This report presents results and experience of the TPS commissioning.

	High-quality and very demanding magnets were designed, fabricated, field quality controlled and installed in the Taiwan Photon Source (TPS). The Storage Ring (SR) lattice is based on double-bend achromat structure with 1.6 nm-rad emittance and slight dispersion in straight sections. The fabrication and field measurement of these magnets were completed in Oct. 2013. The first synchrotron light from TPS storage ring, without applying any corrector at 3 GeV, was observed on Dec. 31, 2014. It indicates that the profile precision and field quality of magnets, and girders alignment reach world class standard. The integral multipoles components of the 240 SR quadrupole and 168 SR sextupole magnets conform to strict specifications. The maximum offset of measured mechanical center in magnets is better than 0.01 mm after feet shimming. The magnetic center offset of the magnets is within 0.02 mm inspected by rotating-coil method. The magnets’ field quality of booster’s pure quadrupole and combined-function quadrupole were accepted according to the errors specifications from beam dynamics and also in the beam commissioning. A permeability study of vacuum chamber was implemented during the booster ring hardware testing. The magnetic field of magnets is distorted by the permeability of vacuum chamber. Study of multipole errors due to magnetized vacuum chamber inside the magnet will be discussed.

The Storage Ring (SR) lattice is based on double-bend achromat structure with 1.6 nm-rad emittance and slight dispersion in straight sections. The fabrication and field measurement of these magnets were completed in Oct. 2013. The first synchrotron light from TPS storage ring, without applying any corrector at 3 GeV, was observed on Dec. 31, 2014. It indicates that the profile precision and field quality of magnets, and girders alignment reach world class standard. The integral multipoles components of the 240 SR quadrupole and 168 SR sextupole magnets conform to strict specifications.
