3. Powerful RF ion sources for fusion

Ursel Fantz (Max-Planck-Institut fuer Plasmaphysik)

3/14/16, 9:40 AM

The neutral beam injection system for the international fusion experiment ITER is based on large and powerful RF-driven ion sources which have to deliver extracted negative hydrogen ion currents of 66 A (H‾) and 57 A (D‾) being accelerated to 870 keV and 1 MeV, respectively. The hydrogen plasma is generated in eight individual cylindrical RF-drivers for which a total RF power of up to 800 kW...

13. Development of a 1 MeV electrostatic accelerator for fusion application at JAEA

Mieko Kashiwagi (Japan Atomic Energy Agency)

3/14/16, 10:10 AM

This paper reports the activities on the development of negative ion accelerators for fusion applications at Japan Atomic Energy Agency (JAEA). In International Thermonuclear Experimental Reactor (ITER) and JT-60 Super Advised (JT-60 SA), high-current and high-energy negative ion beams are required to be produced. The beam currents and energies for ITER and JT-60SA are 40A (200A/m2), 1 MeV for...

4. Determination of plasma parameters via optical emission spectroscopy at CERN’s Linac4 H– ion source

Stefan Briefi (AG EPP, Universität Augsburg)

3/14/16, 10:40 AM

At the accelerator complex of CERN an upgrade of the LHC injector chain is being implemented. This upgrade includes the installation of a linear accelerator based on negative hydrogen ions, the Linac4. The ion source of Linac4 relies on inductive RF coupling with an external coil for discharge generation (RF frequency 2 MHz, maximum RF power 100 kW). In general, the H– ions can be generated...

12. Development, injection and diagnostics for LHD Injectors

Katasuyoshi Tsumori (National Institute for Fusion Science, The Graduate University for Advanced Studies)

3/14/16, 11:20 AM

Neutral beam injector (NBI) is the most powerful and reliable plasma heating device in the nuclear fusion research. The NBI is essential to sustain plasma current generating the confinement magnetic field in TOKAMAK machines such as ITER and JT-60SA. In National Institute for Fusion Science (NIFS), two positive-ion-based NBI (p-NBI) and three negative-ion-based NBI (n-NBI) are installed to...

18. Status of NBI for ITER and the related test facility

Gianluigi Serianni (Consorzio RFX (CNR, ENEA, INFN, UNIPD, Acciaierie Venete SpA))

3/14/16, 12:00 PM

Two Neutral Beam Injectors (NBI) will provide a substantial fraction of the heating power necessary to ignite thermonuclear fusion reactions in ITER. The development of the NBI system at unprecedented parameters (40 A of negative ion current accelerated up to 1 MV) requires a strong demonstration activity, which was endorsed by ITER to optimise the crucial components and systems. A test...

25. Discussion D1: new concepts and spin-off of fusion injectors

Marco Cavenago (LNL), Pierluigi Veltri (LNL)

3/14/16, 12:30 PM

May the large effort in developing powerful ion sources and accelerator produce some spin-off? Which application area? Questions on simulation of multicomponents plasmas (H/D/Cs, 3rd day discussions) and other session topic are also welcomed. Minutes prepared by conveners (P. Veltri, M. Cavenago) may be posted on the website, as well as short presentations (3 slide max) received for...
