“…They provide very efficient, economical and technologically simple way of producing high density uniform plasmas in field of semiconductor [3,4] and fusion technology [5,6]. In fusion grade machines, neutral beam injector (NBI) systems and its related R&D facilities in Europe [7] and in India [8], ICP based negative ion sources are planned to be used due to its low maintenance requirements [9,10]. Geometrical parameters like length, diameter and number of turns of the coil antenna play a big role in coupling RF power into the plasma in ICP [11].…”

Impedance matching circuit between RF generator and the plasma load, placed between them determines the RF power transfer from RF generator to the plasma load. The impedance of plasma load depends on the plasma parameters through skin depth and plasma conductivity or resistivity. Therefore, for long pulse operation of ICPs, particularly for high power (~ 100kW or more) where plasma load condition may vary due to different reasons (e.g. pressure, power, thermal etc.), online tuning of impedance matching circuit is necessary through feedback. In fusion grade ion source operation such online methodology through feedback is not present but offline remote tuning by adjusting the matching circuit capacitors and tuning the driving frequency of the RF generator between the ion source operation pulses is envisaged. The present model is an approach for remote impedance tuning methodology for long pulse operation and corresponding online impedance matching algorithm based on RF coil antenna current measurement or coil antenna calorimetric measurement may be useful in this regard.

“…NIO1 will also host the tests of prototype camera to be used on BES diagnostic of the ITER-like source and injector: SPIDER and MITICA [8,9]. The camera, which employs a 16 bit 2D back illuminated CCD camera with a 1024x 1024 pixels of 13 m, will be soon installed on a BES dedicated spectrometer with 0.5 m focal length, mounting a 1200 gr/mm grating, to be used for the commissioning of NIO1 accelerator.…”

“…To study production and extraction of the beams, resulting from the neutralization of accelerated negative hydrogen-like ions, the SPIDER test facility (particle energy 100keV; extracted beam current 56A and 48A in hydrogen and deuterium respectively) is under construction in Padua (Italy) [2], with the aim of optimising the source operation and of characterising the beam properties. One of the diagnostics [3] dedicated to the SPIDER beam, constituted by 1280 beamlets arranged in 4x4 beamlet groups, will be the Short-Time Retractable Instrumented Kalorimeter (STRIKE) [4], whose main components are one-directional carbon-fibre-carbon-composite (CFC) tiles, observed on the rear side by infrared cameras.…”

The ITER project requires additional heating provided by two injectors of neutral beams resulting from the neutralisation of accelerated negative ions. To study and optimise negative ion production, the SPIDER test facility (particle energy 100keV; beam current 50A) is under construction in Padova, with the aim of testing beam characteristics and to verify the source proper operation. The SPIDER beam will be characterised by the instrumented calorimeter STRIKE, whose main components are one-directional carbon fibre carbon composite tiles. Some prototype tiles have been employed in 2012 as a small-scale version (mini-STRIKE) of the entire system to investigate the features of the beam from BATMAN at IPP-Garching. As the BATMAN beamlets are superposed at the measurement position, about 1m from the grounded grid, an actively cooled copper mask is located in front of the tiles; holes in the mask create an artificial beamlet structure. Recently the mini-STRIKE has been updated, taking into account the results obtained in the first campaign. In particular the spatial resolution of the system has been improved by increasing the number of the copper mask holes. Moreover a custom measurement system has been realized for the thermocouple signals and employed in BATMAN in view of its use in SPIDER. The present contribution gives a description of the new design of the system as well as of the thermocouple measurements system and its field test. A new series of measurements has been carried out in BATMAN. The BATMAN beam characterisation in different experimental conditions is presented
