The synchrocyclotron of the Laboratory of Nuclear Problems for 680 MeV protons with a beam intensity of 2.3 mA and beam extraction efficiency of 5-7%, operational now for 30 years, has been under conversion since 1979. The conversion is aimed at making a phasotron with spatial variation of the magnetic field using the building and the magnetic core of the former accelerator. This spatial variation ensures vertical focusing of accelerated particles in the magnetic field growing along the radius and thus enables a reduction in the frequency range of the accelerating voltage which, in turn, results in a circa three-fold increase in the accelerating voltage and the cycle repetition. The conversion includes replacement of the electromagnetic windings, pole tips, accelerator chamber, dee with the resonance line, rotating capacitor, R.F. generator, ion source, beam extraction system, and auxiliary equipment. A computerized control system, based on microprocessors, will also be implemented. This paper reports the status of the conversion to date.
