DAEδALUS requires three neutrino sources driven by proton beams of ~800 MeV at powers of several megawatts placed at distances of 1.5, 8 and 20 km from the detector. Two cyclotrons working in cascade are chosen to deliver these high power beams. The first cyclotron accelerates the H²⁺ ions beam up to 60 MeV/amu. The beam is then extracted with an electrostatic deflector and reaccelerated up to 800 MeV/amu through a superconducting ring cyclotron. The acceleration of H²⁺ has two advantages: it reduces the space charge effect along the injection and acceleration inside the first cyclotron and allows the extraction of the beam from the last accelerator using a stripper foil. The injector cyclotron can be used in stand-alone mode to drive the IsoDAR experiment, which needs the accelerator placed near an underground neutrino detector. The design and the results of beam dynamic simulations will be shown. the results of preliminary injection and acceleration tests into a cyclotron test bench will be presented.
