16:00 → 17:00 CNPEM's First Superconducting Device Development: A Wavelength Shifter for a Sirius Hard X-ray Beamline

CNPEM is expanding its expertise by developing its first in-house superconducting device – a cryogen-free 6.6 T Superconducting Wavelength Shifter (SWLS) for a Sirius future hard X-ray beamline. This collaborative project with CERN aims to equip CNPEM's Engineering team with the knowledge and experience to build superconducting devices.

The SWLS, designed to produce photons with energy higher than 100 keV, utilizes NbTi coils and holmium poles, targeting an operating margin above 20% at 5 K. A key challenge is achieving a narrow peak field profile (FWHM = 29.8 mm) in the central pole while maintaining the machine's emittance. The design takes advantage of components from a deactivated Superconducting Wiggler, promoting resource efficiency.
