A number of calibration runs (weeks of 24 June 1998 and 17 August 1998) have taken place at the Denver University Atomic Beam facility. This facility is capable of producing mass selected beams of neutral ions at energies from 2 eV to 1 keV with a FWHM of about 1.5 eV.
The neutral beam is produced by having selected negative ions undergo photodetachment by laser radiation. The neutral flux in the beam can be measured absolutely to about 5%.
