Research in the US on heavy ion drivers for inertial confinement fusion
The US study of high-energy multigap accelerators to produce large currents of heavy ions for inertial fusion is centered on the single-pass induction linac method. The large technology base associated with multigap accelerators for high-energy physics gives confidence that high efficiency, high repetition rate, and good availability can be achieved, and that the path from scientific demonstration to commercial realization can be a smooth one. In an induction linac driver, multiple (parallel) ion beams are accelerated through a sequence of pulsed transformers. Crucial to the design is the manipulation of electric fields to amplify the beam current during acceleration. A proof-of-principle induction linac experiment (MBE-4) is underway and has begun the first demonstration of current amplification, control of the bunch ends, and the acceleration of multiple beams. A recently completed experiment, called the Single Beam Transport Experiment has shown that we can now count on more freedom to design an alternating-gradient quadrupole focusing channel to transport much higher ion-beam currents than formerly believed possible. A recent Heavy Ion Fusion System Assessment (HIFSA) has shown that a substantial cost saving results from use of multiply-charged ions, and that a remarkably broad range of options exist for viable power-plant designs. The driver cost at 3 to 4 MJ could be $200/joule or less, and the cost of electricity in the range of 50 to 55 mills/kWhr.
