	While emitting low energy photons from a medium or high energy storage ring, the on-axis heat load on the beam line optics can become a critical issue. In addition, the heat load in the bending magnet chamber, especially in the vertical and circular polarization mode of operation may cause some concern. In this work, we compare the heat loads for the APPLE-II and the Knot-APPLE, both optimized to emit 10 eV photons from the 3 GeV TPS. Under this constraint the heat load analysis, synchrotron radiation performance and features in various polarization modes are presented. Additional consideration is given to beam dynamics effect.

	Development of a cryogenic permanent magnet undu-lator (CPMU) at the Taiwan Photon Source (TPS) is the most recent activity toward a new light source for the Phase-II beamlines. A hybrid-type CPMU with a period length of 15 mm is under construction with PrFeB permanent-magnet materials. A maximum effective magnetic field of 1.77 T at a gap of 3 mm is expected when the magnets (PMs) are cooled down around 77 K. The features desired for the TPS CPMU are low-intrinsic-phase-error characteristics and high thermal budget for various kinds of heat loads. The design of the TPS CPMU is discussed in this paper.

WEPVA127	Design of a 3.5 T Superconducting Multipole Wiggler	3564
	J.C. Jan, C.-H. Chang, H.-H. Chen, S.D. Chen, T.Y. Chung, C.-S. Hwang, F.-Y. Lin, G.-H. Luo NSRRC, Hsinchu, Taiwan
	A 3.5 T superconducting multipole wiggler (SMPW) has been designed through the collaboration of National Synchrotron Radiation Research Center (NSRRC) and Synchrotron Light Research Institute (SLRI). The SMPW will support the hard X-ray source for the X-ray absorption spectroscopy (XAS) beamline in SLRI. The design concept of the SMPW follows from, and improves on, the operating experience of the superconducting magnet in NSRRC. An improvement of the operation and compatible with the cooling capacity of the cryogenic system, is the design goal. A quick and easy recovery of the magnet from a quench event is also required. The design of the magnet circuit and the mechanical of the SMPW are also discussed herein.
