Design of Gridless Ion Mirror for Time Focusing by Energies of Ions in Laser Ion Source

Possibilities of gridless ion mirror usage in conjunction with laser ion source were studied in this paper. This was done in order to get time focusing by energies of ions. Mirror voltages were adjusted so that time focusing by energies of 6th was achieved. This means reduction of time aberrations down to 1 ns. Such a time focusing can be applied to ions with energy spread up to ±20%.
