Retention of the potential energy of multiply charged argon ions incident on copper
Retention of the potential energy of multiply charged argon ions incident on copper
Kentsch, U.; Tyrroff, H.; Zschornack, G.; Möller, W.
The retained fraction of the potential energy of argon ions incident on copper has been measured using stationary calorimetry at charge states up to 9+ and kinetic energies ranging from 75 eV and 240 eV per ionic charge. An average fraction of 30% to 40% is found with little dependence on the charge number and on the kinetic energy. The retention of the total energy ranges 60% to 75% and can mainly be accounted for by the retained fraction of the potential energy and the collisional energy lost by reflected ions and sputtered target atoms.
