The TR24 cyclotron produced and commercialized by ACSI (Canada) delivers a 16-25 MeV proton beam with intensity from few nA up to 500 microA. The bunching of the H⁻ ion beam by means of multi harmonic buncher is considered in this report. The buncher may be installed in the axial injection beam line of the cyclotron. The using of the greed-less multi harmonic buncher will give opportunity to new proton beam applications and to increase the accelerated beam current. The main parameters of the sinusoidal (one-harmonic) and multi harmonic bunchers are evaluated.
