Status of the VICKSI Project

Abstract

The heavy ion accelerator combination VICKSI being built at the Hahn-Meitner-Institut in Berlin consists of a 6 MV single stage van de Graaff accelerator injecting into a 4 sector split pole cyclotron with a mass energy product of K=120. The primary design aim for this accelerator system is to reach 200 MeV for Carbon to Argon ions. The original HVEC Model CN Van de Graaff including the high voltage terminal with ion source is undergoing major reconstruction to achieve the necessary heavy ion performance. All parts of the beam matching system between the two accelerators have been ordered including the stripper and the two bunchers. The cyclotron is built by Scanditronix/Sweden. Three main magnets are completely assembled at the factory for field mapping. Mounting of the first RF-system will be finished around October. Installation of the cyclotron in Berlin is scheduled for 1976 and first trials with beam are anticipated for February 77. The new building for the cyclotron including power- and cooling installation will be ready in 75. Most of the electronics for the computer control of the complete system are delivered. The beam handling between the cyclotron and the target has been designed in detail.
