The relativistic isochronous cyclotron at the Nuclear Research Centre at Karlsruhe (Germany), it uses six equally spaced accelerating gaps, which form part of a system of three quarter-wave resonators. Two of these resonators can be seen projecting from the central vacuum box placed between the poles of the magnet. The magnet itself weighs 280 tons, the pole faces are 225 cm in diameter and are divided into six equal radial sectors : three ' hills ' and three ' valleys A current of more than 200 nA of deuterons at the design energy of 55 SVIeV has already been obtained. md5:509deb3eb524ee6d35077266528087b8	408.0 kB	Preview Download
Diagram of the'spiral-ridge ' pole segments of a two-particle fixed-energy AVF cyclotron designed by Philips Research Laboratories, Eindhoven (Netherlands). The pole diameter is 140 cm and the machine will accelerate protons to 27 MeV or deteurons to 16 MeV. md5:e48b74e1f0c8d3329279e9372fe2f460	76.3 kB	Preview Download
Schematic layout of the proposed 500-MeV isochronous cyclotron for E.T.H., Zurich (Switzerland). This would have eight separate magnets, forming a ring, and four accelerating gaps. Protons would be injected at 70 MeV from the isochronous cyclotron shown at the lower left and accelerated to just over 500 MeV. External beams of protons, pions or muons would be available. md5:46b7906cb9dad2d0fb023e51624627d8	129.9 kB	Preview Download
