Keywords:Electron Cyclotron Resonance Multicharged Ion Source (ECRIS), Accessibility Condition, Upper-Hybrid Resonance

We have considered accessibility condition of electromagnetic and electrostatic waves propagating in an electron cyclotron resonance (ECR) ion source (ECRIS) plasma, and then investigated experimentally their correspondence relationships with production of multicharged ions. It has been clarified that there exists efficient configuration of ECR zones for producing multicharged ion beams, and has been suggested that new resonance, i.e. upper hybrid resonances (UHR), must have occurred.
