Completion of the medium-β section of the ALPI SC-booster at LNL

Abstract The status of the project for the construction of the ALPI superconducting linear accelerator is described, with information on the building, the radiation shield, the beam transport system, the cryogenic system, the machine cryostats, the power and cooling plants, the pulsing system, the beam diagnostic system, the control system, the installation of the resonators in the machine, the niobium QWR development, and the 14.4 GHz electron cyclotron resonance ion source. Details on the plating experience with large scale production of resonators at LNL are also given.
