As part of the High Intensity Proton Injector project
(IPHI), a 6 meters-long aluminum RFQ cold model has
been built. This prototype is designed to elaborate the RF
tuning procedures that will be applied at several steps of
the final cavity machining and assembly. This study has
implied the building of a complete theoretical
modelization of RFQs. The analysis of the measurements
with our formalism can generate slug tuners commands or
capacitances defaults. These capacitances defaults are
transformed into estimation of the longitudinal
distribution of the mechanical disequilibria between the
quadrants of the RFQ whatever the boundary conditions
are. We present the tests that we made to verify the
relation between the mechanical defaults and the
estimated electrical errors. |
