In this work, we investigate the ion flux at a grounded electrode located a
djacent to a pulsed, argon plasma generated by a high-energy electron beam.
The plasmas, produced in 100 mTorr, are characterized by high plasma densi
ties (> 10(11) cm(-3)) and low electron temperatures (< 1.5 eV). An energy
selective mass spectrometer was used to measure temporally resolved ion kin
etic-energy distributions at the electrode surface. In addition, ion energy
distributions are presented for various electrode locations. The ion energ
y distributions correlate well with Langmuir probe measurements of the plas
ma potential. (C) 2001 American Vacuum Society.
