Metal dielectric structures (MD) installed in the plasma chamber of the Frankfurt 14GHz electron cyclotron resonance ion source (ECRIS), have been used to significantly reduce the level of microwave power, necessary to create comparable ion intensities as for the standard operation of the Frankfurt ECRIS. The measurements indicate that the RF-power may be reduced by a factor of 2-3 to obtain the same output of high argon charge states as in the standard source with stainless steel plasma chamber. This reduced level of microwave power also leads to a much lower level of X-ray emission from the source.
