Description
Modern synchrotron light sources are competing intensively to increase X-ray brightness and, eventually, approach the diffraction limit, which sets the final goal of lattice emittance. Recently, we propose a new optics solution aimed at reaching low emittance, using a lattice element “Complex Bend”. The Complex Bend is a sequence of dipole poles interleaved with strong alternate focusing so as to maintain the beta-function and dispersion oscillating at low values. By integrating this element at low emittance lattice, the designed emittance is around 30 pm-rad. To prove the feasibility of this new design, we designed and fabricated the key element, prototype complex bend, with gradient at 140 T/m. It was installed in the beam line with 100-200 MeV beam energy at NSLS-II linac beamline and beam commissioned started in Jan. 2023. In this paper, we report the beam commissioning result.
