The recent advancements in laser-driven ion acceleration techniques using thin foil targets allow the maximum proton energies close to 100 MeV. From a view point of practical applications, high-purity proton beams with high reproducibility are quite advantageous. In experiments using thin foil targets, however, protons from surface contaminants along with the high-z component materials are accelerated together, making the production of impurity-free proton beams unrealistic. \nHere we introduce a micron-size hydrogen cluster, composed of 10^8-10 hydrogen molecules, as a target to generate impurity-free, highly-reproducible, and robust multi-MeV proton beams. Because of the recent progress in intense laser technology, the advanced PW class lasers can now achieve intense laser fields around 10^22 W/cm^2; with such fields, all the electrons inside the micron-size hydrogen cluster up to 3.0 μm in diameter can be fully stripped off, resulting in a pure Coulomb explosion with a pronounced increase in accelerated maximum proton energies scaled as Emax = 276(d/2)2 MeV, where d is a diameter of clusters. For example, 100 MeV protons could be produced via the Coulomb explosion of the 1.2 μm diameter hydrogen cluster when irradiated by a laser pulse with a peak intensity of 1.6 × 10^21 W/cm^2. The robust nature of the Coulomb explosion mechanism offer an additional advantage for practical applications.
