We present the status of ECRIS operation in KVI. Our work is mainly focused on improving the beam intensity and quality of highly charged ions for injection into the AGOR cyclotron. The main request was for Ne6+ ions to produce short-lived 21Na for fundamental physics studies. Typical beam intensities are 350 eμA. Several other ion beams were produced, e.g. C2+, C4+, C6+ and F4+. Overall performance of the source met the user requirements. We recently started again with Pb ion production, resulting in 25 eμA of Pb27+. Source output was gradually optimized, mainly by installing stainless steel screens at the injection and extraction sides of the ion source. A two-frequency heating system (14.5 + 12.5 GHz) has been installed and the first results will be presented.

We discuss a new and versatile emittance meter recently built at KVI. The instrument measures 4D phase-space distributions of low-energy multiply-charged ion beams by scanning a vertical array of 20 micrometer diameter holes horizontally through the beam. The transmitted beamlets are detected with a MCP-CCD camera combination. The emittance meter can measure the full 4D emittance in less than five minutes. We will present a series of emittance measurements, including a systematic comparison with an Allison emittance scanner performed at ISN, Grenoble with the A-Phoenix source, confirming the measurement principle as well as the additional feature to measure the full four dimensional phase-space.
