Abstract

Superconducting undulators (SCUs) with a period of 14.5 mm are under development for the Advanced Photon Source (APS) using Nb3 Sn superconductors. The initial goal is to install a SCU with a 19 to 29-keV tuning range for the first harmonic photon energy. The design of the SCU assembly includes the interface with the beam chamber as an integral part of the assembly. A four-period Nb3 Sn half SCU was fabricated and tested. After a number of quenches, the SCU was charged to an engineering current density of 1.92 kA/mm2 in the coil pack. This corresponds to a peak field of 1.08 T on the beam axis with a pole gap of 8.5 mm. The achieved current density was approximately 90% of the engineering critical current density for the design calculations. With an operating current density of 1.6 kA/mm2, the SCU will operate at a peak field of 0.95 T with some degree of stability. [ABSTRACT FROM AUTHOR]

Abstract

A planar superconducting undulator (SCU) with a period of 15 mm is under development at the Advanced Photon Source (APS). The SCU is designed to achieve a peak field of 0.8 T on the beam axis for an 8 mm pole gap and a current density in the coil of 1.0 kA/mm². Short sections of low-carbon-steel cores with 12 and 22 periods were fabricated, and coil windings were completed with NbTi superconducting wire. After "training" by means of quenches, the SCUs were able to charge up to near the critical current density Jc of 1.43 kA/mm². Using a thin-film heater attached to the inner surface of a vacuum chamber wall, steady-state heat fluxes were applied to the coil/pole face of the 12-period SCU in 4.2 K liquid He (LHe). The heat flux densities needed to quench the SCU were measured. At 0.998jc and 0.8jc the thermal stability margins were about 13 mW/mm² and 2 mW/mm², respectively. The thermal stability margin of the SCU was affected by the latent heat of vaporization of LHe. [ABSTRACT FROM AUTHOR]
