Recent and Future Developments at S.I.N.

The 590 MeV ring cyclotron produces 60-80 ¿A of protons which are mainly used for meson production. A special pulsed mode gives an average intensity of 30-40 ¿A at a repetition frequency of 400 kHz and a duty cycle of 40 %. Recent developments are: computer aided set-up for single turn extraction, periodic centering of beam on target, and closed loop computer control of the magnetic fields of injector and ring cyclotron. A third harmonic flattop cavity is ready for installation. A new injector which will deliver beams of more than 1 mA has been funded and the main efforts are concentrated on buildings, magnets, RF-system, ion source development and computer control. Preparations for the start up of the medical pion applicator are underway. Further goals are: I123 isotope production around the clock and an improved polarised ion source for low energy research. Serious studies for a medium flux slow neutron facility using an intense 590 MeV beam have started.
