The Coupling Impedance of the RHIC Injection Kicker
- Brookhaven National Lab. (BNL), Upton, NY (United States)
The RHIC injection kicker is configured as a "C" cross section magnet with interspersed ferrite and dielectric bricks to approximate a transmission line as shown in Fig. 1. The dielectric bricks replace the lumped capacitors used in the more conventional plate kicker configurations used at other laboratories. This solution was suggested by Cassel as an economical way of building a transmission line kicker and adopted by Forsyth et al in order to achieve the required 95 nsec (1-99%) risetime. The use of ceramic bricks with a relative dielectric constant of ~100 provides the capacitance missing in the original slab ferrite constructions and which now results in a true transmission line kicker. The high dielectric constant entails, however, the danger of high local electric stress, potentially limiting the peak field achievable. Another peculiarity of this solution was observed by Mane et al in the measurement of the longitudinal coupling impedance, which exhibits sharp resonances in the GHz region.
