These chambers are made by glazing together four machined ceramic parts, then brazing on metal parts at the ends to make the vacuum connections. To avoid damaging the other kicker ceramic chambers, we had to limit the machine’s maximum current, in 16-bunches mode. After analysis of the first design, to ensure reliable injection and enable the machine to operate at its nominal current, we had to modify the kicker ceramic chambers to a more robust design. This new design is based on a single-piece ceramic body, in which the internal profile is respected, and then brazed metal parts at the ends to connect to the adjacent chambers. All the complexity of this design lies in the realization of the single-piece ceramic body with the omega shape reduced aperture. PB - JACoW Publishing CP - Geneva, Switzerland ER -
