Workshop on Timing Modes for Low-Emittance Storage Rings

A three-day workshop was held in Lund, Sweden, from March 25 to 27, 2015, with a focus on timing modes for low-emittance storage rings. The MAX IV Laboratory, currently under construction in Lund, will provide a 1.5 GeV storage ring for soft X-rays and a 3 GeV storage ring with an ultralow emittance down to 0.2 nm rad for hard X-rays 1 M.

Both rings are designed to operate with a uniform multibunch filling pattern with a 100 MHz RF system and employ passive harmonic cavities 2 Å.

For the 3 GeV ring, the harmonic cavities are also required to conserve the ultralow emittance at high bunch charge 3 S. C. Leemann, Phys. Rev. ST Accel.
