The goal of the research is the design and construction of a short-period helical undulator for the International Linear Collider (ILC) thereby addressing a specified accelerator-technology requirement. The positron supply for the ILC will be generated by shining a 285 kW beam of 10 MeV photons onto a metallic target. The photons themselves are to be generated from a series of 100 2-m-long short-period double-helical undulator units energized by a 150 GeV electron beam. We plan to develop a special Nb3Sn insulated strand for the winding of the undulator. A three-stage R&D program is planned in which: (1) superconducting strand is developed and manufactured, (2) using this strand, a 14 mm undulator will be wound on an existing armature and tested, (3) based on the results of the tests and some preliminary FEM modeling, recommendations will be made for the design and construction of a 10 mm undulator in a Phase-II continuation.
