Abstract: Superconducting undulators (SCUs) require thermal control of large heat loads for proper operation and to provide high radiation output powers. A conduction cooling apparatus for an SCU device includes a beam chamber having a hollow core inside of the beam chamber along a length of the beam chamber. The hollow core allows charged particles to pass through the hollow core of the beam chamber to generate output radiation. A beam chamber holder is physically and thermally coupled to the beam chamber to maintain a position, and control a temperature of, the beam chamber. At least one magnet is configured to provide a magnetic field to the hollow core, and at least one cooling bar is physically and thermally coupled to the magnet. A cooling source is thermally coupled to both the beam chamber holder and the cooling bar to provide cooling capacity to the beam chamber and the magnet.

Abstract: A helical superconducting undulator includes a cylindrical magnetic core through which a bore hole allows the passage of charged particles. A single superconducting wire wraps the magnetic core guided by helical flights and cylindrical protrusions, to create interleaved helical windings on the magnetic core. An electrical current may be supplied to the superconducting wire to generate a periodic helical magnetic field in the bore. The helical superconducting undulator also includes a strong-back enclosure that acts as an epoxy mold during epoxy impregnation, a structural support to ensure straightness of the undulator after epoxy impregnation, and assists in cooling and thermal control of the magnetic core and superconducting wire during device operation.

A continuous tape is wound about a series of turn around pins and in grooves in a magnetic core. A plurality of winding stacks are created, each transitioning to the next sequential stack by a transition tape portion extending from one turn around pin to the next turn around pin, which is position opposite with regard to the location of the pin on the magnetic core.
