Wendelstein 7-X, a superconducting optimized stellarator built in Greifswald/Germany, started its first plasmas with the last closed flux surface (LCFS) defined by 5 uncooled graphite limiters December 2015. At end of 10 weeks long experimental campaign (OP1.1) more than 20 independent diagnostic systems were operation, allowing detailed studies many interesting plasma phenomena. For example, fast neutral gas manometers supported video cameras (including one fast-frame camera frame rates...
A 60 kV neutral lithium diagnostic beam probes the edge plasma of JET for measurement electron density profiles. This paper describes recent enhancements setup, new procedures calibration and protection measures ion gun during massive gas puffs disruption mitigation. New light splitting optics allow in parallel emission measurements with a double entrance slit CCD spectrometer (spectrally resolved) interference filter avalanche photodiode camera (fast fluctuation studies).
The Wendelstein 7-X (W7-X) fusion experiment is aimed at proving that the stellarator concept suitable for a future reactor. Therefore, it designed steady-state plasmas of up to 30 min, which means thermal control plasma-facing components (PFCs) vital importance prevent damage device.In this paper an overview design Near Real-Time Image Diagnostic System (hereinafter called "the System") PFCs protection in W7-X presented. goal monitor with high risk permanent due local overheating during...
Light reflections are one of the main and often underestimated issues plasma emissivity reconstruction in visible light spectral range. Metallic other specular components tokamak generate systematic errors optical measurements that could lead to wrong interpretation data. Our analysis is performed at data from COMPASS. It a D-shaped with metallic vessel possibility H-mode plasma. Data fast camera were used for tomographic background subtraction study boundary. In this article, we show...
Diagnostic alkali atom (e.g., lithium) beams are routinely used to diagnose magnetically confined plasmas, namely, measure the plasma electron density profile in edge and scrape off layer region. A light splitting optics system was installed into observation of lithium beam emission spectroscopy diagnostic at Joint European Torus (JET) tokamak, which allows simultaneous measurement with a spectrometer fast avalanche photodiode (APD) camera. The reconstruction ∼10 ms time resolution, absolute...
A special video camera has been developed for the 10-camera overview system of Wendelstein 7-X (W7-X) stellarator considering multiple application needs and limitations resulting from this complex long-pulse superconducting experiment. The event detection intelligent (EDICAM) uses a 1.3 Mpixel CMOS sensor with non-destructive read capability which enables fast monitoring smaller Regions Interest (ROIs) even during long exposures. can perform simple data evaluation algorithms...
Abstract A support laboratory has been set up to study pellet production, launch and shattering of cryogenic protium, deuterium, neon pellets for the ITER disruption mitigation system, which plans use 28.5 × 57 mm (diameter length) an mixture in Shattered Pellet Injectors. Such large protium have not produced launched before, therefore desublimation process studied detail two steps. First 19 diameter were produced, followed by demonstration final size. recipes established all types, it was...
In the past few years a ten channel video diagnostics system was developed, built and installed for Wendestein 7-X stellarator (W7-X). The is based on EDICAM (Event Detection Intelligent Camera) CMOS cameras (400 fps @ 1.3 Mpixel). first W7-X experimental campaign (OP1.1) diagnostic not integrated into central control data acquisition of W7-X, therefore development user friendly interface necessary to fulfill following complex requirements: manage configuration all (each with four...
