Columbia University cyclotron, showing the new concentric line radiofrequency system
Abstract/Description: | Columbia University cyclotron, showing the new concentric line radiofrequency system. The radiofrequency power is fed from the oscillator to the background through two small concentric lines up the large concentric lines which extend horizontally from the accelerating chamber at the right. The accelerating electrodes within the chamber are supported on the inner conductors of the two large concentric lines which form, in effect, a quarter wavelength line. The low radiofrequency voltages fed to these large lines are 'stepped-up' to very high voltages on the electrodes within the chamber. The concentric lines give marked improvement in efficiency and produce higher voltage at higher radiofrequencies than systems used heretofore. In addition, all equipment is grounded and shielded during operations. |
