Heating neutral beam (HNB) injectors, necessary to achieve burning conditions and control plasma instabilities in ITER, are characterized by such demanding parameters that a test facility (NBTF) dedicated their development optimization is being realized Padua (Italy) with direct contributions from the Italian government (through Consorzio RFX as host entity) ITER international organization (with kind domestic agencies of Europe, Japan India) technical scientific support various European...
The requirements of ITER neutral beam injectors (1 MeV, 40 A negative deuterium ion current for 1 h) have never been simultaneously attained; therefore, a dedicated Neutral Beam Test Facility (NBTF) was set up at Consorzio RFX (Padova, Italy). NBTF includes two experiments: SPIDER (Source the Production Ions Deuterium Extracted from Rf plasma), full-scale prototype source injectors, with 100 keV accelerator, to investigate and optimize properties source; MITICA, entire injector, devoted...
The EU DEMO Plant Electrical System (PES) main scopes are to supply all the plant electrical loads and deliver Power Transmission Grid (PTG) net power generated. studies on PES during Pre-Concept Design (PCD) Phase were mainly addressed understand possible issues, related special features both of generated, with respect a same size, be supplied loads. For this purpose, approach was start design different components adopting technologies already utilized in fusion experiments Nuclear Plants...
In June 2018 the SPIDER device, which is full-size prototype of negative ion source and extractor for ITER Heating Neutral Beam has entered first operation phase at Test Facility (NBTF) in Padova, Italy. This paper describes present status experimental plans results obtained during campaign radio-frequency driven plasma source.
In JT-60SA, the control of resistive-wall-mode (RWM) instabilities will also be realized with a dedicated active system based on 18 in-vessel sector coils. Each coil fed independently by fast inverter. Due to outstanding dynamic performance required, new insulated-gate bipolar transistor modules silicon carbide (SiC) have been adopted. Being capable switch at 30 kHz, these components, together very system, allow reaching required high simple and compact H-bridge topology. The RWM-PS first...
This paper presents a technique to model electric devices and systems, which cannot be represented adequately with rational transfer functions, integrated in transient simulations. Such has been successfully validated exploited the modeling optimization phase of fast switching converter its load, is coil subject skin, proximity shielding effects. Furthermore, possibility use this order control such investigated, obtaining promising results.
One of the performance limiting factors in Ion Cyclotron Range Frequencies (ICRF) systems for thermonuclear fusion reactors is voltage holding capability launchers. Increased stand-off, hence power density ICRF launchers, would be a desirable feature future reactors. This contribution showcases design IBEX (ICRF Breakdown Experiment), an experimental set-up fundamental studies on Radio-Frequency vacuum arcs, with particular focus effect external plasma triggering mechanism. The experiment...
