The new JET ITER-like wall (made of beryllium and tungsten) is more fragile than the former carbon fiber composite requires active protection to prevent excessive heat loads on plasma facing components (PFC). Analog CCD cameras operating in near infrared wavelength are used measure surface temperature PFCs. Region interest (ROI) analysis performed real time maximum measured each ROI sent vessel thermal map. system started October 2011 has already successfully led a safe landing when hot...
The poloidal distribution of the halo current density on top dump plate in JET can now be measured thanks to a new set Rogowskii coils. These are first measurements able offer an insight width interaction with wall. Therefore they both validation assumption made for disruption design criteria and one additional point extrapolation expected width, hence (and related local electro-mechanical loads in-vessel components) ITER. During upward events, is consistent total current. footprint extends...
Recently, a new recipe for developing and deploying real-time systems has become increasingly adopted in the JET tokamak. Powered by advent of x86 multi-core technology reliability JET's well established Real-Time Data Network (RTDN) to handle all I/O, an official Linux vanilla kernel been demonstrated be able provide performance user-space applications that are required meet stringent timing constraints. In particular, careful rearrangement Interrupt ReQuests' (IRQs) affinities together...
The installation of international thermonuclear experimental reactor-relevant materials for the plasma facing components (PFCs) in Joint European Torus (JET) is expected to have a strong impact on operation and protection experiment. In particular, use all-beryllium tiles, which deteriorate at substantially lower temperature than formerly installed carbon fiber composite imposes strict thermal restrictions PFCs during operation. Prompt precise responses are therefore required whenever...
These days, research on the classification of neutron/gamma waveforms in scintillators using pulse shape discrimination (PSD) techniques is a highly studied topic. Numerous methods have been explored to optimize this classification, with some most recent being focused machine learning excellent results. approaches are mainly based use 1-D convolutional neural networks (CNNs). In field, field-programmable gate arrays (FPGAs) high-sampling rate analog digital converters (ADCs) used perform...
In a tokamak, the accurate estimation of plasma boundary is essential to maximise fusion performance and also first line defence for physical integrity device. particular, wall components might get severely damaged if over-exposed high thermal load. The most common approach calculate geometry related parameters based in large set different types magnetic sensors. Using this information, real-time equilibrium codes infer flux map shape its distance known reference (e.g. wall). These are...
The JET control and data acquisition system (CODAS) is an integrated that provides all the pulse based continuous acquisition, real time slow room interfaces for JET. It has a long history, dating back to beginning of in 1980. utilises both commercially available hardware along with many in-house modules. software grown up evolved largely independently other developments big science. Similarly, on MAST history evolution from previous facilities at Culham (COMPASS). (some shared CODAS)...

Arcs are the potentially most dangerous events related to Lower Hybrid (LH) antenna operation. If left uncontrolled they can produce damage and cause plasma disruption by impurity influx. To address this issue an arc real time control protection imaging system for Joint European Torus (JET) LH has been implemented. The is one of additional heating systems at JET. It comprises 24 microwave generators (klystrons, operating 3.7 GHz) providing up 5 MW current drive JET plasma. This done through...
