Abstract :
An existing lattice made of identical FODO cells can be modified to have adjustable momentum compaction. The modified lattice consists of repeating superperiods of three FODO cells where the cells have different horizontal phase advances. This allows tuning of the momentum compaction or γt (transition) to any desired value. A value of the γt could be an imaginary number. A drawback of this modification is relatively large values of the dispersion function (two or three times larger than in the regular FODO cell design). This scheme also requires an additional quad bus for the modified cells
