• Employed six gratings to cover photon energies from 10 to 1500 eV.

Main Results:

• Achieved expected energy-resolving powers of up to 15,000 (high-energy) and 40,000 (low-energy) at 10 µm slit openings.
• Capable of delivering a photon flux of 1 x 10^11 photons/s at an energy-resolving power of 20,000.
• Designed for efficient utilization with multiple simultaneous end-stations.

Conclusions:

• The new 6 m-SGM beamline represents a significant upgrade in synchrotron radiation capabilities.
• The design enables high-resolution spectroscopy and photonics research across a broad energy spectrum.
• This beamline will facilitate advanced experiments requiring high photon flux and energy resolution.
