MGZh cyclotron for Aabo Academy and its operation

Operational experience of a sector-focusing cyclotron with variable energy from 5 to 20 Z2/A MeV made for the Aabo Academy (Finland) and indended for acceleration of protons, deuterons, helium-3 and helium-4 ions is described. The cyclotron is operated with qualified service personnel of two persons in one shift and mean operating time amounts to 100h in a month. Time necessary for cyclotron preparation for operation and start-up is 20-30 min. Cyclotron maintenance is carried out twice a year, maintenance time is 2-3 weeks. Typical regimes and operating time of the accelerator are given for 4 months in 1978. Nuclear-physical experiments are carried out on the cyclotron, besides it is used for the production of C11, O15, F18, Rb81 isotopes
