Abstract
Absolute ion densities in an Electron Cyclotron Resonance (ECR) ion source plasma have been measured using high resolution X-ray spectroscopy of (n = 2) --> (n = 1) emission lines from highly charged argon ions. Ion densities have been correlated to extracted currents and ion confinement times have been deduced. Confinement time evolution with charge state and plasma perfo rmances is presented and discussed.
