  One of advantages of a compact cyclotron over other type accelerators is a small size mainly defined by the facility’s bending magnetic field. In such cyclotrons an application of an external injection is required in some cases. But for high magnetic field of the cyclotrons (over 4-5 T) there appears a severe problem to make the 1st turns in the machine with external injection of accelerated particles. This paper describes a proposal of a new central region structure of a compact cyclotron that permits one to successfully solve the problem of the axial injection into such a facility using a spiral inflector.

  In the Laboratory of Nuclear Problems of the JINR the possibility of designing of the isochronous cyclotron F250 with the energy of protons 250 MeV on the basis of magnet with the diameter of pole 6 m, which is used for the synchro-cyclotron is examined. Synchro-cyclotron many years works for obtaining the protons with the energy 680 MeV and with the intensity of extracted beam 2.5 mkA. For the solution of medical problems the required energy of protons comprises not more than 250 MeV and depends on the depth of the tumor arrangement inside a patient. For determining the required energy of protons the information about the mean free path of protons in the correspondence for the position of Bragg's peak in each case is used. Necessary energy of protons is obtained by means of degrader system providing a retarding the extracted beam of protons with 680 MeV to 250 MeV and less. In this case the utilized for medical purposes intensity of beam does not exceed 50 nA. The proposed cyclotron F250 will make it possible to strongly decrease the electric power of magnet and to avoid the need of beam degradation from 680 MeV to 250 MeV. For creating the required magnetic field of the cyclotron F250 it is necessary to change the form of steel spiral shims and disks, located inside a vacuum chamber of synchro-cyclotron. The basic parameters of the magnetic system of the cyclotron F250 with the condition of retaining the vacuum chamber and the magnet yoke of synchro-cyclotron are given.

  The isochronous cyclotron DC-280 is intended to accelerate the ion beams with A/Z from 4 to 7 up to the energy 8 – 4 MeV/nucleon. The wide range of the magnetic field levels from 0.64T till 1.32T allows to make a smooth variation of the beam energy over the range ±50% from nominal. For operational optimization of the magnetic field the 11 radial and 4 pairs of harmonic correcting coils are used. The numerical formation of the magnetic field is carried out. The problems and solutions of DC-280 magnetic field design are described.

  Accelerator hadron therapy technique is one of applied researches realized at JINR. The JINR-IBA collaboration has developed and constructed the C235-V3 cyclotron for Dimitrovgrad hospital center of the proton therapy. Proton transmission in C235-V3 from radius 0.3m to 1.03 m is 72% without beam cutting diaphragms; the extraction efficiency is 62%. The main advantage of this cyclotron in comparison with serial commercial cyclotrons of IBA is related to higher current of the extracted beam. The cancer treatment is realized in JINR on the phasotron proton beam. More than 1000 patients were treated there. A project of the demonstration center of the proton therapy is discussed on base of a superconducting 250 MeV synchrocyclotron. The superconducting synchrocyclotron is planned to install instead of phasotron in Medical Technical Complex of DLNP. The project of the medical carbon synchrotron together with superconducting gantry was developed in JINR. The basis of this medical accelerator is the superconducting JINR synchrotron – Nuclotron. One important feature of this project is related to the application of superconducting gantry.

  JINR is one of the leading proton therapy research centers of the in Russia. The modern technique of 3D conformal proton radiotherapy was first effectuated in Russia in this center, and now it is effectively used in regular treatment sessions. A special Medico-Technical Complex was created at JINR on the basis of the phasotron used for proton treatment. About 100 patients undergo a course of fractionated treatment here every year. During last 14 years were treated by proton beams about more than 1000 patients . A project of the demonstration center of the proton therapy is discussed on base of a superconducting 250 MeV synchrocyclotron. The superconducting synchrocyclotron is planned to install instead of phasotron in Medical Technical Complex of DLNP.

  DC-60 heavy ion accelerator, put into operation in 2006, according to its specifications - spectrum, charge and energy of accelerated ions, has the high scientific, technological and educational potential. The highest possible universality both by spectrum of accelerated ions and acceleration energy and regimes was built in DC-60 heavy ion accelerator designing. The new interdisciplinary research complex based on cyclotron DC-60 makes it possible to create a highly-developed scientific-technological and educational environment in the new capital of Kazakhstan. DC-60 accelerator is a dual cyclotron, which is capable of charged particles acceleration up to kinetic energies in MeV/nucleon, expressed in the following relation: E = 60(zi/A)2, where zi - accelerated ion charge, A - atomic weight of ion. Relation (zi/A) in formula must be within the following limits: (zi/A)2 = (1/6 – 1/12), that impose constraints on charge of accelerated ions. Thus, range of ions accelerated on DC-60 cyclotron is 6Li to 132Xe, variation of ion energy is over the range 0.33 to 1.75 MeV/nucleon. Some results of our work carrying out on the base of DC-60 cyclotron in the field of production, acceleration and transportation of charged particles, physics of solid state, nuclear and atomic physics, production of track membranes etc are given in the article. Also it will be reported about modern trends of accelerators development in Kazakhstan.

The production of metal ion beams with ECR ion sources using MIVOC method is described. The method is based on the use of metal compounds having a high vapor pressure at room temperature: for example, C2B10H12, Fe(C5H5)2 and several others. Intense ion beams of B and Fe were produced at the FLNR JINR cyclotrons using this method. The main efforts were went into production and acceleration of 50Ti ion beam at the U-400 cyclotron. The experiments on production of 50Ti ion beam were performed at the test bench with the natural and enriched compounds of titanium (CH3)5C5Ti(CH3)3. In the experiments at the test bench the beam currents of Ti5+ - 80 mkA and Ti11+ - 70 mkA were achieved at different settings of the source. After successful tests two 3 weeks runs with Ti-50 beam were performed at the U-400 cyclotron for the experiments on spectroscopy of super heavy elements. The intensity of the injected beam of 50Ti5+ was about of 50-60 mkA, during experiment the source have shown stable operation. The compound consumption rate was determined to be about of 2.4 mg/h, corresponding to 50Ti consumption of 0.52 mg/h.

  To date, Warsaw U200P cyclotron exploited a mirror inflector to feed heavy ions extracted from ECR ion source (10 GHz, 11 kV) to the central region of the cyclotron. However, in such configuration very low transmission was reachable after many optimizations. Additionally, the new ECR ion source (14,5 GHz, 14-24 kV) was installed, which offers energies far exceeding capabilities of the currently operated inflector and central region. To avoid these obstacles, we have developed a spiral inflector and redesigned central region of the cyclotron. It was a very challenging task, bearing in mind limited volume of central region in our compact machine, to carve these elements suitably for decent versatility of ion beams offered by Warsaw cyclotron. This project was executed in the collaboration with FLNR in Dubna, Russia. The cyclotron equipped with the new central region works in the "constant orbit" regime. Here we present the results of both computational simulations and measurements of the beam transmission in upgraded central region.
