We report on recent upgrades of the ORNL Multicharged Ion Research Facility, and our activities in the area of ECR ion source diagnostic measurements. The upgrades include installation of a new all permanent magnet ECR ion source [1] on a high voltage platform that increases our high energy beam production capability to 250keV/q, and installation of a floating beamline fed by a 10 GHz CAPRICE ECR ion source for producing decelerated ion beams to energies as low as a few eV/q range. The primary application of all the produced ion beams is to study fundamental collisional interactions [2] of multicharged ions with electrons, atoms, and surfaces. We also summarize recent diagnostic measurements of the ECR plasma potential and other plasma parameters using an in-situ Langmuir probe installed in the ECR edge plasma and complementary measurements [3] using an external beam deceleration method.

MOCOCK01	PK-ISIS: a New Superconducting ECR Ion Source at Pantechnik	ion, extraction, ECR, ion-source	26

	The new ECR ion source PK-ISIS was recently commissioned at Pantechnik. Three superconducting coils generate the axial magnetic field configuration while the radial magnetic field is done with multi-layer permanent magnets. Special care was devoted in the design of the hexapolar structure, allowing a maximum magnetic field of 1.32 T at the wall of the 82 mm diameter plasma chamber. The three superconducting coils using Low Temperature Superconducting wires are cooled by a single double stage cryo-cooler (4.2 K). Cryogen-free technology is used, providing reliability, easy maintenance at low cost. The maximum installed RF power (18.0 GHz) is of 2 kW. Metallic beams can be produced with an oven (Tmax = 1400 °C) installed with an angle of 5° with respect to the source axis or a sputtering system, mounted in the axis of the source. The beam extraction system is constituted of three electrodes in accel-decel configuration. Description of the source and results of the magnetic measurements will be given. Performances of the source in terms of beam intensities and charge states distribution will be presented.

Takahashi RIKEN, Saitama, Japan
	A place of an activity of ECR ion sources is not only ion source on a heavy ion accelerator facility. A highly ionization efficiency, flexibility of ionized sample, low consumption rate in sample, and non-equilibrium ECR plasma, etc. that a ECR ion source have, may be needed in other fields at time. We have developed several kinds of small ECRISs that have customized for the analysis. The purposes of the analysis are, precise measurement of isotope ratio of a metal element, detection of chemical warfare agents, and detection of produced molecular (or fragment) ions by the ECR plasma. In this workshop, we will report the compact ECRISs by a permanent magnet type for the analytical system.

MOPOT012	Tests of the Versatile Ion Source (VIS) for High Power Proton Beam Production	emittance, extraction, plasma, proton	61

	The sources adapted to beam production for high power proton accelerators must obey to the request of high brightness, stability and reliability. The Versatile Ion Source (VIS) is based on permanent magnets (maximum value around 0.1 T on the chamber axis) producing an off-resonance microwave discharge. It operates up to 75 kV without a bulky high voltage platform, producing several tens of mA of proton beams and monocharged ions. The microwave injection system and the extraction electrodes geometry have been designed in order to optimize the beam brightness. Moreover, the VIS source ensures long time operations without maintenance and high reliability in order to fulfil the requirements of the future accelerators. A description of the main components and of the source performances will be given. A brief summary of the possible options for next developments of the project will be also presented, particularly for pulsed mode operations, that are relevant for some future projects (e.g. the European Spallation Source of Lund).

TUPOT003	A New BETSI Test Bench at CEA/Saclay	plasma, ion, diagnostics, solenoid	117

	By the 90s, CEA has undertaken to develop the production of high intensity light ion beams from plasma generated by electron cyclotron resonance (ECR). Important results were obtained with the SILHI source in pulsed or continuous mode. Presently, CEA/Saclay is now involved in the construction of different injectors dedicated to large infrastructures like IFMIF or Spiral 2. Other installations are also interested by high intensity ion sources like ESS or FAIR. To improve and test new sources, a new test bench named BETSI (Banc d'Etudes et de Tests des Sources d'Ions) is now operating for several months. Low energy beam line diagnostics consist of a Faraday cup, cameras and a species analyzer. The SILHI emittance scanner can also be installed on the beam line. On this test bench, different permanent magnet source configurations are tested. In order to modify plasma chamber size and shape, a new ECR source design is developed. An experimental study of the plasma visible light emitted through electrodes was implemented on BETSI using a monochromator. Extracted beam intensity of a permanent magnet source is compared to plasma light emission. Results obtained with monochromator will be compared with SOLMAXP code in order to explore radio frequency wave and plasma interaction.
