3D Design of the IPHI RFQ Cavity

Pascal Balleyguier (CEA Bruyeres-le-Chatel)

Starting from 2D Superfish-based simulations, we studied the IPHI RFQ cavity from a 3D resonator point of view. The task was to give dimensions for a complete 3D mechanical design. This has been done by some analytical developments and localized constant models. Many 3D simulations were made with MAFIA, either to confirm some theoretical prediction or to give an accurate dimension for some localized detail. Among the many questions studied were: synthesis of the required voltage law, dimensioning RFQ ends, studying resonant coupling, RF losses, peak field, dipolar stabilizer rods, WG inputs... Some of the conclusions have been tested on our cold model.
