Implications of Beam Timing on Kicker Operation
The timing structure of a beam on the kicker operation is discussed, showcasing various scenarios and proposed pulse trains. The impact of different pulse modes, cycle lengths, bunch lengths, and pulse separations on the kicker operation is evaluated through detailed analysis and comparisons. The content presents insights into optimizing beam timing for efficient kicker operation in a scientific setting.

A.M., December 4, 2104 IMPLICATION OF THE TIMING STRUCTURE OF BEAM ON THE KICKER OPERATION Materials used: [1] Phil Adamson, Timing of Muon Campus , November 20, 2014. [2] Mary Convery, Proton Beam to the Muon Campus , November 25, 2014. STATEMENT Any time structure does not affect operation of the kicker pulsed PS as soon as the fastest repetition rate remains 100 Hz (10 ms between pulses). THE END
