The injection kicker system for the muon G-2 experiment

The muon g-2 experiment is designed to measure the anomalous magnetic moment of the muon to an accuracy of 0.35 ppm by measuring the difference between the spin precession frequency and the cyclotron frequency of the particle in a known magnetic field. The injection kicker is designed to deflect 3.094 GeV/c muons by an angle of 10 mrad into a storage ring with a radius of 7.112 m. No magnetic materials can be used in or near the beam line because of the high precision with which the field of the main dipole magnets must be known. Eddy currents induced in the vacuum chamber by the fast kicker pulse, and their effect on the main dipole field must also be considered. An air core magnet which is driven by an underdamped capacitor discharge modulator using a spark gap switch has been designed. This design, as well as test data, will be presented.
