CW Mode of Operation of a Proton FFAG Accelerator

In a previous note we have studied a Fixed-Field Alternating-Gradient (FFAG) Accelerator for a Proton Driver with 1.0 GeV kinetic energy and average beam power of 10 MWatt. The mode of operation discussed for that facility was a pulsed mode with a repetition rate of 1 kHz, probably the highest feasible for such an accelerator with a single-turn beam circulating at any time. The duty cycle is then modest, determined by the length of the extracted beam pulse length of 0.77 µs corresponding to a circumference of 201.8 m. The duty factor is 0.077%, useful for several applications like, for instance, Pulsed Spallation Neutron Sources. But other applications would still require possibly a Continuous Wave (CW) mode of operation with 100% duty cycle. Such factor can be obtained in Cyclotrons and Super-Conducting Linacs (SCL). It would be highly desirable if a CW mode of operation can also be made possible in an FFAG Accelerator.
