The ITER Neutral Beam Test Facility (NBTF), called PRIMA (Padova Research on Megavolt Accelerator), is hosted in Padova, Italy and includes two experiments: MITICA, the full-scale prototype of heating neutral beam injector, SPIDER, full-size radio frequency negative-ions source. NBTF realization exploitation SPIDER MITICA have been recognized as necessary to make future operation injectors efficient reliable, fundamental achievement thermonuclear-relevant plasma parameters ITER.

The ITER project requires additional heating by two neutral beam injectors, each accelerating to 1 MV a 40 A of negative deuterium ions, deliver the plasma power about 17 MW for one hour. As these requirements have never been experimentally met, it was recognized as necessary setup test facility, PRIMA (Padova Research on Megavolt Accelerator), in Italy, including full-size ion source, SPIDER, and prototype whole injector, MITICA, aiming develop injectors be installed ITER. This realization...
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...
SPIDER is one of the two projects ITER Neutral Beam Test Facility (NBTF) under construction in Padova, Italy, at Consorzio RFX premises; it will have a 100 keV beam source with full-size prototype radiofrequency (RF) ion for Injector (NBI), designed to operate pulse length up 3600 s, featuring ITER-like filter field configuration, caesium oven layout and wide set diagnostics.These features allow reproducing operation like as cannot be done any other existing test facility.SPIDER realization...

Specific emphasis is placed on thermal, structural, electrical designs components, order ensure their compatibility with criteria specified for ITER vessel i.e.,...
Regulated high-voltage power supplies (RHVPSs) are important sources in high-power heating and current drive systems for a tokamak. Along with high at output, these meet the requirements of fast dynamics (on order few microseconds), low ripple factor, good output regulation. A development overview is presented RHVPS ranging from 14 to 80 kV several-megawatt typical results. Having extensive tests performed an 80-kV 75-A RHVPS, it being regularly used neutral beam injector (NBI) Institute...

This article describes hardware and software solutions to a need which is comprised of (i) acquisition large volume high speed data with multiple time scales, (ii) control various operational parameters device diagnostics, (iii) processing management the acquired for plasma device. The solution relies on base VXI bus uses standard PC Windows 98/NT operating system C as programming language. networked existing network result allowing storage space facilities from any terminal in laboratory.
This paper describes the ITER ICRF system main requirements and latest developments for its different parts which are to be procured by Parties. The built in margins will allow reaching on a large parameter range, or delivering more power restricted range.
Regulated High Voltage Power Supplies (RHVPS) are commonly used in high-energy particle accelerators. RHVPS is a modular power supply which kV level modules (40 or 80#) cascaded to generate desired of voltage/power [1]. One the most challenging tasks involved provide input number rectifier with required isolation (inter-winding and winding ground). This accomplished by deploying multi-secondary (large numbers, say 40 secondaries) transformers. concept was realized for first time country...
High voltage power supply (HVPS) based on pulse step modulation (PSM) topology has already demonstrated its ability for broadcast transmitters, accelerators using radio frequency (RF) source and neutral beam injectors. Typical ion cyclotron resonant heating (ICRH) system composed of cascaded connection driver stage end would need two supplies. A novel concept tapping outputs from single PSM HVPS is attempted the first time. developed with dual output to feed stages a high RF amplifier. This...
Regulated High Voltage Power Supplies (RHVPS) are developed at the Institute for Plasma Research (IPR) Neutral beam and RF heating applications of Steady-state Superconducting Tokomak (SST-1) up to 80 kV, 130A rating. They deliver power loads that have very low fault energy tolerance; thereby protection load is mandatory. At each stage special diagnosis necessary protect supply components. Also, output done so not more than 10J. Multi-secondary transformers (2 numbers, 5.6 MVA rating with 40...
