WAVELENGTH DISPERSIVE MEASUREMENTS OF CHARACTERISTIC K X-RAYS OF AN ECR KRYPTON PLASMA

X-rays from different transitions of the K series were used to analyze components of the ion charge state distribution inside a microwave he ated krypton plasma. It is shown that X-ray transitions involving oute r-shell electrons show spectra with clearly resolvable satellite lines arising from low charged ions. In contrast to the evaluation of K-alp ha spectra this allows to get information about the ion charge state d istribution in the low ionization region.
