abstract = {The laser acceleration of proton beams with
quasi-monoenergetic features in the energy spectra from
microdot targets is investigated by numerical simulation.
The formation of these spectral peaks is strongly dependent
on the interplay between different ion species in the
target. The scaling of the spectral peak's energy, and
number of protons in the spectral peak, with both microdot
composition and laser intensity is considered. Particular
attention is given to determining the proton concentration
below which the number of protons in the spectral peak
rapidly diminishes. It is shown that at proton
concentrations of 1-5n(crit) a spectral peak is produced
that reaches an energy up to $70\%$ of the maximum proton
energy, whilst still containing more protons than would be
produced by a conventional target in this energy range.},
