STUDY, CONSTRUCTION AND TEST OF A 3 GHZ PROTON LINAC- BOOSTER (LIBO) FOR CANCER THERAPY

In a collaboration between CERN, the Universities and INFN of Milan and Naples, and the TERA Foundation, a 3 GHz, 200 MeV proton Linac-Booster (LIBO) operating from 62 to 200 MeV has been studied. LIBO is a modular structure in OFE copper consisting of nine modules, of which the first (62 to 74 MeV) is constructed as a prototype, to be tested with RF power in the year 2000. Each module is fed by a klystron and is composed of four tanks connected via bridge couplers, all brazed together. Permanent magnet quadrupoles are housed in the bridge couplers and between the modules. The design, construction and tests are described with particular emphasis on the transfer of this technology to industry.
