Abstract
Electron Beam Ion Source (EBIS) has been one of the widely used table-top devices for the production of highly charged ions due to its high purity of charge states. At Korea Multipurpose Accelerator Complex (KOMAC), we have constructed a compact EBIS test bench, consisting of an EBIS-A (advanced EBIS, Dreebit GmbH), a Wien filter and a Faraday cup. The Wien filter with a permanent magnet is designed to separate charge states of ion beams produced from the EBIS-A. A fast extraction system is incorporated in the EBIS test bench to produce ion beams of a pulse width < 1 µs. We characterize the EBIS test bench with He and Ar gases. Here, results on the characterization will be discussed in detail. We also plan to install an EBIS-SC (superconducting EBIS, Dreebit GmbH) as a <1 µs proton pulse injector to the KOMAC proton linac. Beside the commercial EBIS’s, a 7 Tesla (T) EBIS is currently under development at KOMAC and will be used as an ion beam injector for a 200 MHz Radio-Frequency Quadrupole accelerator. Here, we briefly discuss the plans for the EBIS-SC and on-going development on the 7 T EBIS design.
