THACH01	Indirect Cooled Superconductive Wiggler Magnet	vacuum, damping, cryogenics, ion	140
	K. Zolotarev BINP SB RAS, Novosibirsk, Russia
	Superconducting wigglers are very popular devices for generation of the synchrotron radiation in the hard X-ray spectral range. The one direction of the future progress in wigglers development is reducing of the technical complexity wigglers design as well as technical service for cryogenic system. The BINP wigglers without liquid helium consumption were a noticeable milestone of these efforts. The next significant step toward additional simplification wiggler design and service is indirect cooling of the wiggler magnet. In this case the wiggler magnet not sinked into the liquid helium, but cooled by thermal connection link with the head of cryogenic cooler. This approach is used for design of the indirect cooled wiggler for IMAGE beamline on the ANKA light source (KIT, Germany). This wiggler also will be tested as a prototype for damping wiggler for the damping rings in the project of the Compact Linear Collider (CLIC) for CERN. This report summarizes some details of the wiggler design as well as a result of the short prototype testing.

WEPPD002	Simulations and Design of THz Wiggler for 15-40 MeV FEL	simulation, electron, radiation, power-supply	569
	E. Syresin, S.A. Kostromin, R.S. Makarov, N.A. Morozov, D. Petrov JINR, Dubna, Moscow Region, Russia
	The electromagnetic wiggler is applied for narrow-band THz radiation in the 30 mkm to 9.35 mm wavelength range. This is a planar electromagnetic device with 6 regular periods, each 30 cm long. The end termination pattern structure is +1/4,-3/4,+1,…,- 1,+3/4,-1/4. This structure is more appreciable for compensation of the first and second fields, especially, to provide the small value of of second integral of 500 G*cm². The peak magnetic field is up to 0.356 T, it is defined by large wiggler gap of 10² mm and available capacity of water cooling system of 70 kW. The parameter is varied in the range K=0.5-7.12 corresponding to a field range B=0.025-0.356 T peak field on axis. The wiggler is used in 15-40 MeV at beam currents up to 1.6 mA. The bunch compression scheme allows the whole wavelength range to be covered by super-radiant emission with a sufficient form factor. The wavelength range corresponds to 217 mkm - 9.35 mm at electron energy of 15 MeV, it is equal to 54 mkm - 2.3 mm at electron energy of 30 MeV and it is 30 mkm - 1.33 mm at electron energy of 40 MeV. The 3D Opera simulations and design of THz wiggler is under discussion.

WEPPD021	HTS Wiggler Concept for a Damping Ring	damping, multipole, dynamic-aperture, radiation	599
	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.
