Microcomputer controlled energy variation of an isochronous cyclotron and beam handling system
- 1. Bonn Univ. (Germany, F.R.). Inst. fuer Strahlen- und Kernphysik
Description
An automatic 3 MeV variation of a 30 MeV A-beam was performed in 300 steps at the Bonn Isochronous Cyclotron. A microcomputer in connection with a control unit adjusted the cyclotron and the monochromator system parameters. This combination allowed a direct and precise measurement of broad excitation functions. Using fast magnetic field stabilization an energy-shift was accomplished to an accuracy of better than 1 part in 105 within 20 s. The stability of the beam position on the target was about 0.05 mm.
