A new high efficiency, resolution, fast γ-ray spectrometer was recently installed at the JET tokamak. The is based on a LaBr3(Ce) scintillator coupled to photomultiplier tube. digital data acquisition system used allow spectrometry with event rates in excess of 1 MHz expected future DT plasmas. However, lower typical present day experiments, digitization can degrade energy resolution system, depending algorithms for extracting pulse height information from digitized pulses. In this paper,...
High resolution γ-ray spectroscopy measurements at MHz counting rates were carried out nuclear accelerators, combining a LaBr <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> (Ce) detector with dedicated hardware and software solutions based on digitization off-line analysis. Spectra measured up to 4 MHz, little or no degradation of the energy resolution, adopting pile rejection algorithm. The reported results represent step forward...
We here present the principles and main physics capabilities behind design of radial gamma ray spectrometers (RGRS) system for alpha particle runaway electron measurements at ITER. The diagnostic benefits from recent advances in gamma-ray spectrometry tokamak plasmas combines space high energy resolution a single device. RGRS as designed can provide information on particles time scale 1/10 slowing down ITER 500 MW full power DT scenario. Spectral observations 3.21 4.44 MeV peaks reaction...
Abstract High-resolution γ-ray measurements were carried out on the Joint European Torus (JET) in an experiment aimed at accelerating 4 He ions MeV range by coupling third harmonic radio frequency heating to injected beam. For first time, Doppler broadening of peaks from 12 C(d, pγ) 13 C and 9 Be(α, nγ) reactions was observed interpreted with dedicated Monte Carlo codes based detailed nuclear physics processes. Information confined deuteron energy distribution inferred, energies as high 6...
Abstract The paper presents an overview of the design status Radial Neutron Camera (RNC), that, together with Vertical Camera, will provide, through reconstruction techniques applied to measured line-integrated neutron fluxes, time resolved measurement ITER and α-source profile (i.e. emissivity, neutrons emitted per unit volume). RNC is composed two subsystems, In-Port Ex-Port located, respectively, inside outside Plug Equatorial Port #01. subsystem in a more advanced stage since it has...

The efficient vertical stabilization (VS) of plasmas in tokamaks requires a fast reaction the VS controller, for example, after detection edge localized modes (ELM). For controlling effects very large ELMs new digital control hardware, based on Advanced Telecommunications Computing Architecture™ (ATCA), is being developed aiming to reduce loop cycle (down an optimal value 10μs) and improve algorithm performance. system has 1 ATCA™ processor module up 12 modules, each one with 32 analog input...
A multi-input-multi-output controller for the plasma vertical stabilization was implemented and installed on Joint European Torus tokamak.
