Requirements of A Proton Beam Accelerator for An Accelerator-Driven Reactor

When we first proposed am accelerator-driven reactor, the concept was opposed the physicists who had earlier used the accelerator for their physics experiments. This opposition arose because they had nuisance experiences in that the accelerator was not reliable, and very often disrupted their work as the accelerator shut down due to electric tripping. It is still not infrequent to have tripping of the accelerator during physics experiments. While the might be tolerable in experimental work if it does not occur too frequently, for the industrial use of accelerator, such as for power generation, the possibility of shutting off the accelerator by tripping must be eliminated; even a once-a-year stoppage is very destructive for supplying electricity energy. To prevent this, a multiple-channeled accelerator beam was suggested; however, this approach become uneconomical. The operation of a storage ring for a synchrotron radiation facility is required to be very stable beam-track operation, otherwise, precise measurements cannot be carried out with an unstable photon beams. Stable beam operation is now successful even when it is not accelerating the particle. (Author)
