	This paper presents the results of the calculation of the magnetic system of the cyclotron for accelerating of multicharged ions developed at NIIEFA JSC. The cyclotron complex is designed to generate ions with a mass-to-charge ratio in the range A/Z= 3/7, accelerate them to energies in the range of 7.5-15 MeV per nucleon. The cyclotron electromagnet has a four-sector structure, with a pole diameter of 4 m. Radial coils placed on the poles under the sectors are designed to adjust the magnetic field for providing isochronous acceleration conditions for different ions. A group of azimuthal coils designed to correct the first harmonic of the magnetic field and to center the orbits of the accelerated ion, as well as to ad-just the position of the axial symmetry plane of the magnetic field is located on the sectors. The required magnetic field topology for ion acceleration was formed in the induction range of 1.29-1.6 T. Calculations were per-formed for the 1/8 part of the electromagnet. A mode was chosen in which the dependence of induction on the radius, which provides isochronism, is realized due to the shape of "iron". For this mode with an induction in the center of 1.44 T, the shape of side plates, plugs, and sec-tor chamfers was determined. The currents in radial coils and the main dynamic characteristics of the cyclotron magnetic field for ion acceleration in the energy control range were calculated using the obtained magnetic field maps.

WEPSC07	Medium Energy Ions Transport Channel for a Pulsed Linear Accelerator	MEBT, cavity, simulation, rfq	355
	V.S. Dyubkov MEPhI, Moscow, Russia
	For a transportation and matching proton and light ion beams (the maximal value A/Z is about 3.2) between RFQ and groups of IH-cavities it is suggested medium energy ions transfer line. That line should provide 100% beam transmission under negligible beam envelope increase and small longitudinal beam size growth during particle transport. MEBT consists of two parts. One of them provides ion transfer with energy 820 keV/u and the second one provides ion transfer with energy 2.46 MeV/u.

	Funding: Ministry of Education, Science and Technological Development of the Republic of Serbia. FAMA is a user facility for materials science with low energy ions beams in the Vinca Institute of Nuclear Sciences, Belgrade, Serbia. It includes a heavy ion source, a light ion source, two channels for modification of materials, and two channels for analysis of materials. Recently, designing of a channel for transmission studies within FAMA, the C3 channel, has begun. The initially planned studies are related to the rainbow effects with electrostatic very thin lenses (VTLs) and two-dimensional (2D) materials. In the former case, the main aim is to develop a method for generation of narrow ion beams, to be used, for example, in materials science and technology. The main aim in the latter case is to determine precisely the interaction potential of the projectile and target atoms. In both cases, the theoretical basis of the explorations is the theory of crystal rainbows. From the technological point of view, construction and use of the C3 channel includes the following challenges: (i) production and diagnostics of the narrow and parallel ion beams to be directed to the chosen VTLs and 2D materials, (ii) registration of the transmitted ion beams with high resolution 2D position sensitive detectors, (iii) preparation of the 2D materials and maintaining their cleanliness during the measurements, and (iv) providing the ultra-high vacuum conditions in measurements with the 2D materials.
