Sd. Kravis et al., FEASIBILITY OF PHOTOIONIZATION OF MULTICHARGED IONS AND A FIRST TEST OF A PHOTON-BEAM ION-SOURCE (PHOBIS) WITH THE RIKEN EBIS (REBLS), Physica scripta. T, T71, 1997, pp. 121-126
The importance, feasibility and method for measuring the photo-ionizat
ion cross-section of multi-charged ions using the RIKEN Electron Beam
Ion Source (REBIS) is discussed. Specifically the cases for the 2 s an
d 1 s photo-ionization of Ar14+ is explored. It is concluded that such
measurements are possible today and in future (3(rd) generation) sync
hrotron radiation facilities, and will be carried out upon modificatio
ns of the apparatus. Also described, is the first test of a PHOton Bea
m Ion Source using REBIS. It's potential advantage over other ion sour
ces is that in the ion production mechanism photoionization the recoil
ions obtain only near thermal energies to making ion beams with very
low energy spread possible.
