Abstract:
It is proposed to use a Side Coupled Linac (SCL), starting
at 30MeV, up to 230MeV for protontherapy. The linac
consists of 25 modules (two tanks each). Twelve 3GHz
power generators feed two modules each in parallel and
one power generator feeds the last module. The SCL is
designed, assuming a mean accelerating field in the
cavities of 16,5MV/m. The longitudinal and transverse
beam dynamics have been studied, assuming that the
input parameters emittance, energy spread and mean
current are those of commercial 30MeV cyclotrons. The
characteristics of the output beam were analysed: the
transmittance value is largely sufficient to deliver a
correct dose for therapy; the beam line activation is kept
largely below allowed levels; the output energy spread is
sufficiently small. The first prototype module is under
construction and a second one is under design. Contacts
with e2v have been established for defining an agreement,
which foresees to use magnetrons as feeders for the
acceleration tests. Attention was therefore paid to phase
locking constraints among feeders. Theoretical studies
suggest that transmittance is not significantly affected if
de-phasing is kept into values that seem attainable with
phase-locked magnetrons. A first investigation was
performed on the possibility of resorting to a 18MeV
cyclotron. The results were stimulating.
