Buncher
Drift
(E) rotator
Cooler
System would capture both signs(+, -)
OPTIMIZATION IS NEEDED
Use ofTaylor seriesleads to tricky way of handling beams with large coordinate spread (and that is exactly the case) Relative coordinates should be < 0.5 (empirical fact)
synchronous particle
equations in deviations from synchronous particle
nonlinear oscillator
COSY Infinity uses similar coordinates
40-50 maps 12-15 maps
Potential calculation time reduction. Implementing.
OPTIMIZATION?
