The IFMIF-EVEDA* Linear IFMIF Prototype Accelerator (LIPac) is a 9 MeV, 125 mA CW deuteron accelerator to validate the technology to be used in the future IFMIF accelerator. The acceleration of deuterons will be done through two stages. The matching between them will be done in the Medium Energy Beam Transport line (MEBT). In this section, the transverse focusing of the beam is carried out by five quadrupole magnets with integrated steerers, grouped in one triplet and one doublet**. These magnets have been designed by CIEMAT, and manufactured by the Spanish company ANTECSA. After manufacturing, they were fully characterized at ALBA-CELLS magnetic measurements facility. In this paper we describe the characterization bench used to measure the magnets, the measurement protocol and the alignment procedure, as well as the results obtained and the iteration process followed in order to shim the magnets to fulfill with beam dynamics requirements.

For very high intensity linacs, both beam power and space charge should be taken into consideration for any analysis of accelerators aiming at comparing their performances and pointing out the challenging sections. As high beam power is an issue from the lowest energy, careful and exhaustive beam loss predictions have to be done. High space charge implies lattice compactness making the implementation of beam diagnostics very problematic, so a clear strategy for beam diagnostic has to be defined. Beam halo becomes no longer negligible, and it plays a significant role in the particle loss process. Therefore, beam optimization must take the halo into account and beam characterization must be able to describe the halo part in addition to the core one. This presentation discusses advanced concepts and methods for beam analysis, beam loss prediction, beam optimization, beam diagnostic and beam characterization especially dedicated to very high intensity accelerators.
