Abstract

1,039,137. Particle accelerators. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 4, 1964 [July 29, 1963], No. 30675/64. Heading H1D. A particle accelerator employing cyclotron resonance acceleration has a curved, as shown annular, gap 19 across which the particles are simultaneously accelerated in many different orbital paths by an R.F. electric field applied between the hollow electrodes 9, 10 bounding the gap. The particles attain maximum orbits 26 which are caused to precess around the vacuum chamber due to a weakening of the transverse magnetic field at the periphery due to flux leakage. The magnetic polepieces on either side of the vacuum chamber are tapered to keep the flux density approximately constant across the poles. The accelerated particles are diverted to the outside of the chamber by deflecting electrode 20. The frequency of the applied R.F. field may be equal to the cyclotron frequency of the particles, but preferably the third harmonic is chosen. The ion source is shown at 11 and additional ions may be produced by impact with hydrogen gas in the chamber. The electrodes are water-cooled. Coaxial feed lines 22 for the R.F. pass through the polepieces and are connected to the centres of the electrodes 9. The structural frame of the accelerator chamber may be formed of stainless steel, brass, copper-alloy, or bronze plates or castings. The chamber lids are of soft iron.
