	The problem of the effective low-energy linac design is of interest to many fields of science, industry and medicine. It is well known that nonsynchronous harmonics of RF field (RF undulator) are focusing the particles. Analytical beam dynamics investigation can be carried out by means of the averaging method over the rapid oscillations period (the so-called smooth approximation) in the oscillating fields. Motion equation is presented in the form of the Hamilton's equations. Motion integrals are found by means of Poincare mapping.

	A.V. Smirnov RadiaBeam, Santa Monica, USA A.A. Mikhailichenko CLASSE, Ithaca, New York, USA
	A new design for the proposed ILC damping ring (DR) is based on 2G HTS cabling technology applied to the DC windings with yoke and mu-metal-shimmed pole to achieve ~2 T high-quality field within a 86 mm gap and 32-40 cm period. Low levels of current densities (~90-100 A/mm²) provide a robust, reliable operation of the wiggler at higher heat loads, up to LN₂ temperatures with long leads, enhanced flexibility for cryostats and infrastructure in harsh radiation environment, and reduced failure rate compared to the baseline SC ILC DR wiggler design at very competitive cost.
