Description
Since many years the TERA Foundation is working on
"cyclinacs", novel accelerators
which produces a beam particularly suited for the many
paintings spot-scanning
technique of moving tumour targets. Indeed the beam from a
cyclinac has repetition
rates in the range 200-400 Hz, as necessary for painting
many times the target, while
the energy and the charge delivered to the next voxel can be
chosen electronically
(i.e. without moving absorbers), as needed for spot-scanning
with fast transverse and
longitudinal feedback corrections.
After explaining the working principle of a cyclinac and
the prototype work done
on a 3 GHz linac for protons and carbon ions, two projects
will be described: IDRA
and CABOTO. They are based on (i) a 30 MeV proton
cyclotron, used also to produce
radioisotopes for diagnostics and endoradiotherapy, and (ii)
a 300 MeV/u carbon ion
cyclotron, which is used for the protontherapy of deep
seated tumours.
