✦ Synopsis

An all-permanent magnet electron cyclotron resonance (ECR) ion source is tuned to create a variety of intense molecular ion beams for basic research. Based on simultaneous injection of several gases with spectroscopic high purity or enriched isotope content (e.g., H 2 , D 2 , N 2 , O 2 or CO) and low power microwave heating, the ECR ion source produces diatomic molecular ion beams of H

,4 and possibly higher. Molecular ion beams have been produced with very high current intensities compared to other molecular beam sources. The recorded molecular ion beam spectra are discussed.
