	The use of the K130 cyclotron during the past few years has been normal. The total use of the cyclotron in 2012 was 6441 hours out of which 4610 hours on target. Three quarters of the beam time was devoted to basic nuclear physics research and one quarter for industrial applications, the main industrial application being space electronics testing. Altogether over 20 different isotopes were accelerated in 2012. Beam cocktails for space electronics testing were the most commonly used beams (26 %). Since the first beam in 1992 the total run time for the K130 cyclotron at the end of 2012 was 124’138 hours, and altogether 32 elements (73 isotopes) from p to Au have been accelerated. The MCC30/15 cyclotron will deliver proton and deuteron beams for nuclear physics research and for isotope production. The experimental set-up has been mainly under construction and we have had only a couple of beam tests. Isotope production with the MCC30/15 cyclotron has suffered from severe administrative delays. Finally in December 2012 a preliminary budget study for a GMP laboratory for FDG production (18F) was done. Decisions on the radiopharmaceuticals production at JYFL will be done during 2013.

	A new gradient corrector with active coils has been developed for beam focusing and bending in the extraction region of the RCNP AVF cyclotron. The gradient corrector is a quadrupole type consisting of a pair of a C-type iron yoke. A sixteen-turn hollow conductor was coiled around each side yoke, and the two iron dipoles generate a linear field gradient independently. A field gradient up to 9 T/m is available for focusing a heavy ion beam with magnetic rigidity up to 1.6 T-m. The position of the gradient corrector is manually changeable within ±20 mm from a beam extraction base line. A field measurement was carried out with a Hall-element and we confirmed generation of the designed field gradient under excitation of the main coil. We have succeeded in focusing an extracted beam at an object point of the beam transport optics by a combination of the gradient corrector and a triplet quadrupole magnet following the gradient corrector. Correction of an extracted beam orbit was also demonstrated by optimizing the coil current and position of the gradient corrector. We will report the design and performance of the new gradient corrector.

	Funding: The Mitchell Family Foundation and Texas ASE Fund A superconducting strong focusing cyclotron is being developed for high current applications. Alternating-gradient focusing is provided by an array of ~ 6T/m superconducting beam transport channels which lie in the sectors along the arced beam trajectory of each orbit of the cyclotron. The ~1T sector dipoles, corrector dipoles, and Panofsky type quadrupoles utilize MgB2 superconductor operating in the range 15-20 K. The quadrupole windings make it possible to produce strong focusing of the transverse phase space throughout acceleration. The trim dipole makes it possible to maintain isochronicity and to open the orbit spacing at injection and extraction. The design, development and prototype progress will be presented.

WEPPT006	Design of Achromatic Bends for the High Energy Beam Transport System of HCI at IUAC Delhi	DTL, ion, beam-transport, optics	332
	A. Mandal, D. Kanjilal, S. Kumar, G.O. Rodrigues IUAC, New Delhi, India
	The high energy beam transport system of the High Current Injector (HCI) being currently developed at IUAC will transport beam of maximum energy ~ 1.8 MeV/u with mass to charge ratio (A/q) equal to 6 from drift tube linac (DTL) to the superconducting LINAC in the zero degree beam line of the existing 15UD Pelletron. The whole transport path (~40 m) consists of four 90 degree bends. Since the beams coming from DTL are expected to have an energy spread of 0.5 %, the magnetic bends have to be achromatic. The transport system is designed to meet the restrictions imposed by the existing beam hall and the other space constraints. The first three 90 degree achromats have the configuration of Q1Q2Q3MQ4MQ3Q2Q1 and the fourth one has configuration of Q1Q2MQ3Q4Q4Q3MQ2Q1 where Q stands for magnetic quadrupole and M stands for 45 degree bending magnets. Each achromat has been designed so that its total length is restricted to 7 m to fit into the available space. The maximum dispersion occurs at the middle of Q4. Standard beam dynamics codes like GICOSY* and TRACE 3D** have been used to design the achromats and details of optics will be presented. H.

	Formation by means of octupole magnets of a uniform ions distribution in the existing beam line of U400M cyclotron has been studied. The simulation was performed for Ar¹⁷⁺ ions with energy of 41.3 MeV/amu. The required level of beam non-uniformity on the target with diameter of 60 mm is ±7.5%. Two octupoles with static magnetic fields have been used to achieve the desired uniformity of the beam density in both coordinates simultaneously. The results of calculations are presented. This method of improving the uniformity of the beam will be implemented soon in Flerov laboratory of JINR.
