Studies on low energy beam transport for high intensity high charged ions at IMP
Abstract
Superconducting Electron Cyclotron Resonance ion source with Advanced design in Lanzhou (SECRAL) is an advanced fully superconducting ECR ion source at IMP designed to be operational at the microwave frequency of 18–24 GHz. The existing SECRAL beam transmission line is composed of a solenoid lens and a 110° analyzing magnet. Simulations of particle tracking with 3D space charge effect and realistic 3D magnetic fields through the line were performed using particleincell code. The results of the beam dynamics show that such a low energy beam is very sensitive to the space charge effect and significantly suffers from the secondorder aberration of the analyzing magnet resulting in large emittance. However, the secondorder aberration could be reduced by adding compensating sextupole components in the beam line. On this basis, a new 110° analyzing magnet with relatively larger acceptance and smaller aberration is designed and will be used in the design of low energy beam transport line for a new superconducting ECR ion source SECRALII. The features of the analyzer and the corresponding beam trajectory calculation will be detailed and discussed in this paper.

The nonlinear {delta}F formalism based on the VlasovPoisson equations is used to describe the propagation of a matched, highintensity ion beam through a periodicfocusing solenoidal field in the thinbeam approximation (r{sub b}{lt}S). The distribution function F{sub b} is divided into a zeroorder part (F{sub b}{sup 0}) plus a perturbation ({delta}F{sub b}) which evolve nonlinearly in the zeroorder and perturbed field configurations. To illustrate the application of the technique to axisymmetric, matchedbeam propagation, nonlinear {delta}F simulation results are presented for the case of a periodic solenoidal focusing field in which the (oscillatory) coupling coefficient {kappa}{sub z}(s) turns on adiabatically about amore »

Nonlinear {delta}F simulation studies of highintensity matchedbeam propagation in periodicfocusing transport systems

The distribution function F{sub b} is divided into a zeroorder part (F{sub b}{sup 0}) plus a perturbation ({delta}F{sub b}) which evolve nonlinearly in the zeroorder and perturbed field configurations.

Effect of the plasma electrode position and shape on the beam intensity of the highly charged ions from RIKEN 18 GHz electroncyclotronresonance ion source
Beam intensities of highly charged Ar ions (Ar{sup 11+,12+}) were measured as a function of plasma electrode position. We observed that the beam intensity of Ar{sup 11+,12+} increased when putting the electrode far from the electroncyclotronresonance zone. On the other hand, lower charged heavy ions (Ar{sup 8+,7+}) dramatically decreased. We observed that the intense beam extraction strongly affects the plasma condition. It may be due to the ion pumping effect.
