  We propose an experiment for the first proof of the type I electric
Aharonov-Bohm effect in an ion interferometer for hydrogen. The performances of
three different beam separation schemes are simulated and compared. The
coherent ion beam is generated by a single atom tip (SAT) source and separated
by either two biprisms with a quadrupole lens, two biprisms with an einzel-lens
or three biprisms. The beam path separation is necessary to introduce two metal
tubes that can be pulsed with different electric potentials. The high time
resolution of a delay line detector allows to work with a continuous ion beam
and circumvents the pulsed beam operation as originally suggested by Aharonov
and Bohm. We demonstrate, that the higher mass and therefore lower velocity of
ions compared to electrons combined with the high expected SAT ion emission
puts the direct proof of this quantum effect for the first time into reach of
current technical possibilities. Thereby a high coherent ion detection rate is
crucial to avoid long integration times that allow the influence of dephasing
noise from the environment. We can determine the period of the expected matter
wave interference pattern and the signal on the detector by determining the
superposition angle of the coherent partial beams. Our simulations were tested
with an electron interferometer setup and agree with the experimental results.
We determine the separation scheme with three biprisms to be most efficient and
predict a total signal acquisition time of only 80 s to measure a phase shift
from 0 to 2$\pi$ due to the electric Aharonov-Bohm effect.
