Typical ion therapy centers use particle rates up to … WebGas Cluster Ion Beams impact a surface with very low energy, down to as little as 1 eV per atom. At such low energies they sputter material without modifying the surface chemistry, i.e. without breaking bonds. Low energy sputtering removes just a few nanometres of material at a time, for extremely high-resolution depth profiling.
