Abstract:
In the last decade the focus of research at the ISL shifted from nuclear to solid state physics and ion beam applications. The beam time durations for the experiments became shorter and the flexibility in respect to ion species, energies and currents had to be increased. Furthermore the long and short time stability of the beams for the experiments became more important. One step to fulfill the various demands of the heterogeneous community of ion beam users at ISL was the installation of a Supernanogan ECR-source on a high voltage platform in the former tandem tower. In conjunction with a specifically developed RFQ-structure the source is used as one injector for our (k=132) cyclotron for the production of high energetic ions (1.5 ¿6 MeV(u)) with high currents. Now equipped with the last model of Supernanogan and after several modifications at the source and the platform as well, we are able to deliver noble gas beams with high stability. For the studies of extremely strong electronic excitations of condensed matter the users request heavy high energetic ions. For this purpose we started the production of gold ions with the standard oven from Pantechnik in 2001. Several beam times have been realized already successfully. The improvements will be presented, and the possibilities for further developments of the injection system will be discussed.
