With the Bonn Isochronous Cyclotron either protons, deuterons, alpha particles or other light ions with a charge-to-mass ratio ≥ 1/2 are accelerated to a kinetic energy ranging from 7 to 14 MeV per nucleon. The extracted beam is guided to one of five experimental sites via a high-energy beamline.
To ensure a controlled beam transport via this beamline, the beam is stabilized in angle and position by the beam preparation system after extraction from the cyclotron. This is achieved by fixating the beam position in two consecutive locations. Using pairs of adjustable scrapers which are symmetrically aligned horizontally and vertically around the design orbit one can deduce the relative beam position in the transversal plane. This is done by comparing the beam scrape-off current at the scrapers when the beam is passing between them. Using the relative beam position as feedback for a control loop, the respective beam deviation from the design orbit can be minimized by using dedicated corrector magnets.
In this talk, the design and development of a new digital readout and control of the beam preparation system, which replaces the current analog one, will be presented.
