  There is great need for high intensity proton beams from compact particle
accelerators in particle physics, medical isotope production, and materials-
and energy-research. To address this need, we present, for the first time, a
design for a compact isochronous cyclotron that will be able to deliver 10 mA
of 60 MeV protons - an order of magnitude higher than on-market compact
cyclotrons and a factor four higher than research machines. A key breakthrough
is that vortex motion is incorporated in the design of a cyclotron, leading to
clean extraction. Beam losses on the septa of the electrostatic extraction
channels stay below 50 W (a factor four below the required safety limit), while
maintaining good beam quality. We present a set of highly accurate
particle-in-cell simulations, and an uncertainty quantification of select beam
input parameters using machine learning, showing the robustness of the design.
This design can be utilized for beams for experiments in particle and nuclear
physics, materials science and medical physics as well as for industrial
applications.
