- Abstract
- Negative ion sources are a fundamental component of advanced Neutral Beam Injectors (NBI), which needs to
be strongly optimized in the perspective of DEMO reactor. A relatively compact RF ion source, named NIO1,
with 9 beam apertures for a total H
-current of 130 mA, 60kV accelaration voltage, is being tested and installed
at Padua, in Consorzio RFX, to provide a test bench for source optimizations in the framework of the
accompanying activities insupport to the ITER NBI test facility.
Source magnetic configuration is a minimum B magnetic bottle, which requires placing magnets also behind
the RF coil. There are three acceleration grids, named plasma grid, extraction grid and postacceleration grid,
followed by a repeller electrode for a better control of the space charge compensation of the extracted beam.
Accelerated H
-can be dumped on calorimeter with 283 small sampling holes, and a segmented cooling circuit.
Most critical cooling circuits were obtained with electrodeposition techniques, while numerous cooling channel
for source magnet multipoles were carved in copper and closed by brazing, aiming at sustaining a continuous
beam power of 9 kW and rf power below 5 kW.
Plan and status of the overall installation, including the 70 kV/ 50 kVA insulation transformer powering a high
voltage deck and a optical cavity ring down spectrometer are here summarized and reported. Plasma and low
voltage beam operations are discussed. Development of the Fast Emittance Scanner and preliminary tests of
sampling beam calorimeter atLNL are also discussed. (literal)
