 note = {A cyclotron originally has an excellent energy efficiency, defined by a ratio of beam power to operation power, because a cyclotron is a compact machine consisting of a minimum number of magnets and RF resonators. We are now designing and developing a high intensity compact cyclotron with energy efficiency of 30 % or more to provide mA-order intense beams of proton, deuteron, 4 He2+, H2 +, H- , D- . The key technologies to realize such a high-energy efficiency cyclotron are production of several tens to 100 mA ion beams by positive and negative ion sources, enhancement of high intensity beam transmission and injection efficiency from LEBT to a center region of a cyclotron, improvement of a charge stripping extraction system for a negative intense beam, maximization of energy efficiency of a cyclotron by reducing power consumption in magnet and RF resonator systems. The high energy-efficiency cyclotron will be applied for mass production of RIs and secondarily produced intense neutron flux for BNCT and neutron-induced RI production. In this paper, the conceptual design of a high intensity compact cyclotron to improve energy efficiency is presented.},
