TUP22 | Production of Intense Metal Ion Beams at the DC-60 Cyclotron | 136 |
|
||
Funding: This work was supported by MES RK IRN under grant number AP05133476. In 2017-2018, research program of the DC-60 cyclotron (Astana Branch of the Institute of Nuclear Physics, Kazakhstan) requests acceleration of intense ion beams of solid elements. Beams of B and Fe ions are produced in ECR ion source by using the volatile compounds, while ions of Li, Mg, P and Ca are produced by evaporation from an oven. Beams of 56Fe10+, 7Li1+, 24Mg4+, 31P5+, 40Ca7+, and 11B2+ ions were accelerated up to energies of 1.32-1.75 MeV/u. |

WEB1 | Simulations of ECRIS Performance for Different Working Materials | 170 |
|
||
Free parameters of Numerical Advanced Model of ECRIS (NAM-ECRIS) are selected such as to reproduce the experimental charge-state-distribution of the extracted argon ions for the DECRIS-PM source tuned to produce the maximized Ar8+ currents. Using these fixed parameters, we calculate the extracted currents for Kr, Xe and Bi ions in mix with oxygen, for Ca in mix with helium, and for pure O and He plasmas. Comparison is made with the experimental data, good correspondence is observed. | ||

THC4 | Development of Compact 2.45 GHz ECR Ion Source for Generation of Singly-Charged Ions | 202 |
|
||
2.45 GHz ECR ion sources are widely used for production of single charged heavy ions and secondary radioactive ion beams. This paper describes the development of a compact ECR ion source based on coaxial quarter wave resonator. The first results of extracted current measurements at different resonator configuration as a function of UHF frequency, power and gas flow are presented. At the extraction voltage about of 10 kV and UHF power about of 100 W more than 500 µA of He+ ions were produced with the extraction hole of 3 mm in diameter that corresponds to the current density of 7.5 mA/cm2. | ||
