Summary:

The relationship between Balmer-α and Fulcher-band emissions with extracted H+, H+2 , and H+3 ions
is demonstrated for a 2.45 GHz microwave discharge. Ion mass spectra and optical measurements of
Balmer-α and Fulcher-band emissions have been obtained with aWien Filter having an optical viewport
on the plasma chamber axis. The beam of approximately 1 mA is analyzed for different plasma
conditions simultaneously with the measurement of light emissions both with temporal resolution.
The use of visible light emissions as a valuable diagnostic tool for monitoring the species fraction of
the extracted beams is proposed.
