In 2017, the 200 µA proton beam development was conducted, and in 2018, the production of high power beam from 20 kW to 52 kW had been delivered successfully to the beam dump. Due to the successful construction of 435 tons magnet for CYCIAE-100, it has been proved that the gradient adjustment of magnetic field along radius can effectively enhance the vertical focusing during the isochronous acceleration. This key technology was applied to the general design of a 2 GeV CW proton accelerator, the energy limitation of the isochronous machine is increased from ~1 GeV to 2 GeV, by our contribution of the beam dynamics study for high energy isochronous FFAG. This paper will introduce CIAE’s engineering experience of precision magnet, high power RF systems, and the advantages of beam dynamics simulation based on large-scale parallel computing. The cost-effective solution for such a 2 GeV high power circular accelerator complex will be presented in detail after the brief introduction about the high power proton beam production by the CYCIAE-100.
