NSLS-II Concept

NSLS-II Machine Concept

  • New Electron Storage Ring

  • Medium Energy (3 GeV)

  • Large Current (500 mA)

  • Superconducting RF

  • Top-Off Operation

  • DBA30 Lattice

  • Ultra-Low Emittance (<1 nm)

  • Damping Wigglers

  • Large Dipole Bend Radius (25 m)

  • Provision for IR Source

  • Three-pole wiggler x-ray sources

Selected Technical Challenges

  • Lattice Design: dynamic aperture, energy acceptance

  • Source Stability: vibrations, thermal issues, feedback

  • Impedance Budget: Small gap (5 mm) ID tapers, etc

  • Insertion Device R&D: CPMUs, EPUs, SCUs
