	Double elliptically polarized undulator (DEPU) for a soft X-ray beamline for ARPES and PEEM is being built at SSRF. In DEPU, two EPUs with different period lengths have the roughly same magnet array lengths and share a common H style frame. The shift driving systems for polarization adjustment, which are set on top of the backing beams for the constraint of space, are sophisticated designed to assure position stability under longitudinal magnet force change. Finite-element analyses are also performed to guarantee the rigidity of the systems. The system performance is tested under full operation range and the results are described in this paper.

	A new harmonic coil bench has been developed at Shanghai Institute of Applied Physics (SINAP) to measure the ALS combined function sextupole magnets. The measurement system has been designed with the aim to perform precise, fast and reliable measurements of series of magnets. It determines the strength, and the multipole content of the field as well as the magnetic axis for precise positioning of alignment targets on top of the multipoles. The multipole, while supported on a marble platform, can be moved with regard to the rotating coil using multi-dimensional adjustment plate. The resolution of the movement is read out by micrometer with a few μm resolutions. This article introduces the measurement system constitutes.
