DESIGN AND CONSTRUCTION OF AN RFQ-DRIFTTUBE-COMBINATION FOR A MEDICINE SYNCHROTRON *

The GSI-design proposed for the facility for radiotherapy of cancer tumours with ions at the Radiologische Universitaetsklinik in Heidelberg has been approved by the german "Wissenschaftsrat" last year. The design and construction of the RFQ section of the LINAC system in front of the synchrotron is our contribution to this project [1]. Design studies have been done with respect to the construction and operation costs as well as to a comfortable handling of the machine [2]. Therefore the direct combination of drifttubes with the RFQ electrodes has been examined in detail by beam dynamic simulations.
