- Obviously squeeze with separated beams
- Partial squeezing possible.
- Need to maintain separation at parasitic crossings
- Need to maintain mechanical aperture a
- Need to maintain stability at collimators
- Length of time:
- No of matched intermediate optics:
Mechanism
- Download of current function (t) to power converters (principally
insertion quads, but also correctors circuits as required)
- Squeeze initiated with timing event
- Time limited by power converter response. Functions should be smooth and
avoid zero crossing where possible
