Status of the INS 176cm Sector Focusing Cyclotron

The INS SF cyclotron is a multi-particle variable-energy accelerator and has been in operation since 1974. The maximum energy usable for experiments is 35 MeV for protons, 34 MeV for deuterons, 90 MeV for 3He and 68 MeV for α-particles. Up to 8 μA of these beams are extracted. A cold cathode PIG source for heavy ions was developed and extracted beams of 4.3 μA 14N5+ and 1.5 μA 20RNe6+ are obtained. Polarized protons are axially injected and about 15 nA are deflected. The beam transport system consists of low, medium and high resolution courses. Eleven target stations are available for experiments and eight of them are ready for use. The high resolution course is a double monochrometer system, which can also be operated in a non-dispersive mode. This paper describes the beam development since routine operation started.
