<p>A charged particle accelerator comprising a charged particle generator, a deflection electromagnet, accelerating means, and a vacuum duct. Acceleration is conducted for first and second acceleration periods (22, 23). An acceleration electric field produced by accelerating means is applied from the start (25) of the first accelerating period (22) to the end of the second accelerating period (23). A constant defection magnetic field is applied for the first acceleration period, and an increasing deflection magnetic field is applied for the second acceleration period. The charged particle accelerator has a small size, generates a large output, and enables large current acceleration.</p> |
