  We present a fast and Quasideterministic protocol for the production of
single ions and electrons from a cloud of laser cooled atoms. The approach is
based on a two-step process where first a single Rydberg atom is photo-excited
from a dipole-blockade configuration and subsequently ionized by an electric
field pulse. We theoretically describe these excitation-ionization cycles via
dynamical quantum maps and observe a rich behavior of the ionization dynamics
as a function of laser Rabi frequency, pulse duration and particle number. Our
results show that a fast sequential heralded production of single charged
particles is achievable even from an unstructured and fluctuating atomic
ensemble.
