Abstract

The facilities at the National Accelerator Centre (NAC) are utilized for proton and neutron therapy, the production of radioisotopes and for nuclear physics experiments. This implies an operating schedule with nine energy changes per week. Mainly due to this the reliability of beam delivery deteriorated to such an extent that we recently had to revert to a beam schedule with only four energy changes per week. This necessitated redefinition of the priorities for our proton therapy program. The request for higher proton beam currents at 66 MeV, for radioisotope production, stimulated the design of dedicated flat-top systems for both the light-ion injector cyclotron (SPC1) and the separated-sector cyclotron (SSC). We also investigated the feasibility of accelerating high-intensity proton beams (500µA) in the SSC by using the highintensity space-charge mode developed at PSI. The design of a vertical beamline and modifications to the existing beam transport system for the new high-intensity target station are in progress. Further developments include an additional septum magnet for the SSC extraction system and a new Local Area Network computer-control system for the RF systems. The progress with these projects will be presented and the status of the facilities discussed. [ABSTRACT FROM AUTHOR]
