Electron Beam Ion Sources (EBIS) are powerful tools to produce ions over a wide ion charge spectrum for nearby all elements. A wide spectrum of very different applications of EBIS is known. The EBIS are used in basic research as well as in applications of different fields of technology but also in conjunction with particle accelerators. With the Dresden EBIS ion source family compact ion sources for the production of highly charged ions (HCIs) as platform technology for a wide field of applications are available. The Dresden EBIS-A is a compact, long-term stable room-temperature ion source and the Dresden EBIS-SC a new superconducting high-current EBIS for the production of high currents of HCI. Significant parameters of these ion sources are compared in the present paper. This paper discusses the performance of the presented ion sources for the production of HCIs, compare the sources with other existing machines and discusses the usability of the Dresden EBIS sources in connection with different types of accelerators. It is shown that the sources are particularly suitable for applications in medical particle therapy. The outstanding properties of the EBIS favor them for use with CYCLINACS, Rapid Cycling Medical Synchrotrons and complex synchrotron based medical irradiation facilities.

The technical performance of ion sources of the Electron Beam Ion Source (EBIS) type has substantially improved during the last years. This is demonstrated by proof-of-principle experiments which have been done using a room temperature EBIS, a so-called Dresden EBIS-A, which has been in use for several years. A new superconducting EBIS, a so-called Dresden EBIS-SC, has been taken into operation. With the expected higher beam intensities the Dresden EBIS-SC will offer a compact and low-cost solution for applications in particle therapy and will be applicable for synchrotron based solutions (single- or multi-turn injection) as well as other accelerator schemes. It is shown that the introduction of the Dresden EBIS-SC will simplify the injection beam line of medical accelerator facilities.
