Gap Structure

To demonstrate the large potential of proton minibeam radiotherapy (pMBRT) as a new method to treat tumor diseases, a preclinical proton minibeam radiation facility was designed. It is based on a tandem Van-de-Graaff accelerator providing a 16 MeV proton beam and a 3 GHz linac post-accelerator (designs: AVO-ADAM S.A, Geneva, Switzerland and ENEA, Frascati, Italy). To enhance the transmission of the tandem beam through the post-accelerator by a factor of 3, two drift tube buncher units were designed and constructed: A brazed 5-gap structure (adapted SCDTL tank of the TOP-IMPLART project (ENEA)) and a non-brazed low budget 4-gap structure. Both are made of copper. The performance of the two differently manufactured units was evaluated using a 16 MeV tandem accelerator beam and a Q3D magnetic spectrograph. Both buncher units achieve the required summed voltage amplitude of 42 kV and amplitude stability at a power feed of less than 800 W.

Boron Neutron Capture

A neutron source comprised of a vacuum insulated tandem accelerator and a solid lithium target is in operation for development of boron neutron capture therapy and other applications. The size of the proton beam on the target surface depending on the proton beam current was measured using an infrared camera and thermocouples inserted inside the target. The absence of a noticeable influence of the space charge on the transportation of the proton beam from the accelerator to the target at a distance of 5 m has been established, which simplifies the operation of the neutron source.
