Constant frequency cyclotrons with spirally ridged poles

This report on spirally ridged cyclotrons has require revision in the manner discussed at the January 1955 New York meeting of the American Physical Society. This is due to Laslett's determination of the influence of the scalloped orbit on focusing. To make semi-relativistic particles circulate in a cyclotron at constant frequency and in orbit that are approximately circles, it is necessary to have the average magnetic field increase with radius. This gives rise to vertical (axial) defocusing. The possibility of overcoming this defocusing by the addition of alternating gradient effects is considered here. The spirally ridged (Mark V) type of pole is tried and we will follow the course of trying to avoid integral, half integral, and sum resonances regardless of the structural difficulties to exhibit the problems. Subsequent possible compromises for easing these difficulties will then become evident.
