We report progress we have made in the production of negative hydrogen and deuterium atomic ions in magnetically-confined microwave-driven (2.45 GHz) ion sources. The influence of source surface material, microwave power, source ga,sprgssure and magnetic field configuration on the resulting ion current is discussed. ResulK strongly suggest tha~at least in our source, vibrational]y excited molecular hydrogen, the precursor to atomic negative ion production, is produced via a surface mechanismdoi:10.2351/1.5059114 fatcat:2kfkwxhxevdezfs5ajo6rrclne
