Abstract
The Frankfurt superconducting EBIS has been run beyond the space-charge neutralization limit making use of the evaporative cooling technique showing a continuous transition between EBIS to EBIT operation. The experience gained on the performance of this more sophisticated source has been employed to develop simpler EBIS sources: The MEDEBIS using a warm solenoid will demonstrate rapid extraction of bare nuclei for single turn injection into a synchrotron for cancer therapy. The PPM-focused EBIS with permanent magnets and the XEBIS without any focusing magnetic field have been developed to demonstrate by its reduced power consumption and size to be more suitable to small laboratories. High emission current densities from a laser heated tip cathode offer the formation of a well-defined high current density beam.Several spectrometers have been built and installed to offer diagnostics for the EBIS operation as well as atomic physics research. Ionization measurements can be performed using the magnetic switchyard, an external electrostatic and magnetic spectrometer allows to study secondary electron emission by highly charged ions as well as to ionize and analyse sputtered atoms.
