B = ~1 T.km @ 250GeV
Step at center?
Stored Energy W ~ 125[J] @0.25T
3cm x133 units
Large Test Core for JPARC
Q <1 for non-cut core
Q~10 for cut core @a few mm gap
High B, low core loss
High B, low core loss, high Tc
FT-3L is the best option here.
Two RF in One
Two RF in One
Two RF in One: Two cosine components superposition
(if 2 sides OK)
Separate RF: Each component for each separate kicker
Separate two RF system for the latter two options.
Phase slip for in-bunch can be compensated by phasing. ––> less perturbation
MA has been used for RF accelerating cavity to generate high voltage(V==BS). –> Not for generation of B. ( R&D! )
The number units 133 reduces a serious hazard. (133 cores, 133 Amp’s)
Upgradable to 1TeV(6MHz) –– Two sets?
Easier than Crab-cavity
