•The CESR-TA experiment has been repeated at SLS (PSI-Villingen)
• Result: SLS factor 10…50 more stable than CESR-TA,
but still completely excluded to use for direct validation.
• Assume: any circular machine has similar rest eigenmotion of beam,
use extracted beam in spectrometer like configuration.
• No light source has extraction channel for particle beams
• Only a few machines have “constant spill” slow extraction
• JLAB has CW extracted beam
