We propose an experiment for the first proof of the type I electricAharonov-Bohm effect in an ion interferometer for hydrogen. The performances ofthree different beam separation schemes are simulated and compared. Thecoherent ion beam is generated by a single atom tip (SAT) source and separatedby either two biprisms with a quadrupole lens, two biprisms with an einzel-lensor three biprisms. The beam path separation is necessary to introduce two metaltubes that can be pulsed with different electric potentials. The high timeresolution of a delay line detector allows to work with a continuous ion beamand circumvents the pulsed beam operation as originally suggested by Aharonovand Bohm. We demonstrate, that the higher mass and therefore lower velocity ofions compared to electrons combined with the high expected SAT ion emissionputs the direct proof of this quantum effect for the first time into reach ofcurrent technical possibilities. Thereby a high coherent ion detection rate iscrucial to avoid long integration times that allow the influence of dephasingnoise from the environment. We can determine the period of the expected matterwave interference pattern and the signal on the detector by determining thesuperposition angle of the coherent partial beams. Our simulations were testedwith an electron interferometer setup and agree with the experimental results.We determine the separation scheme with three biprisms to be most efficient andpredict a total signal acquisition time of only 80 s to measure a phase shiftfrom 0 to 2$\pi$ due to the electric Aharonov-Bohm effect.
