Paul Scherrer Institut 5232 Villigen PSI EURISOL/BENE_2007, PSI /GF34 Injector 1 Variable energy cyclotron built by Philips. Its one-piece magnet has an azimuthally varying magnetic field for vertical focusing even at relativistic energies. The beam energy up to 72 MeV for protons. Equipped with several ion sources, Injector 1 offers a wide variety of beams ranging from protons and deuterons to light and heavy ions. Polarized beams of protons and deuterons are also available. Commissioned in In 1994 an ECR ion source was installed to extend its ability to accelerate heavy ions. Typical Beam Properties -Emittance: for all beams 30 mm mrad - Energy resolution: dispersionless mode E/E down to 2.5 x 10-3, analysed mode E/E down to 2 x Intensity: p up to 30 µA - Time structure: The pulse repetition rate is 16.9 or 50.6 Mhz for 72 MeV protons.
