Abstract

In order to allow proper operation of the IFMIF RFQ, it is necessary to perform a campaign of RF measurements on the cavity aimed, on one hand, at determining the basic RF parameters (frequency, Q0, etc.), on the other hand at verifying the fulfilment of the voltage law within the specified admitted range (±2% target value, ±4% acceptance value) of any of the perturbative components upon successive tuner settings as predicted by the tuner algorithm. These measurements also involve the determination of the proper depth of the end plates and the positioning and length of the Dipole Stabilizers (if any). In this contribution the tuning procedure and the results of such measurements will be presented for the case of the IFMIF RFQ will be described.
