The damping rate of the n = 1 toroidal Alfven eigenmodes (TAE) mode in Ohmic-heated JET plasmas has been measured and compared with the prediction of the kinetic NOVA-K code, which includes electron and ion Landau damping of the global shear-Alfven wave fi ...

Design and R&D of an ECRH system on JET

Stefano Alberti, Hartmut Zohm

An electron cyclotron resonance heating (ECRH) system has been designed for JET in the framework of the JET enhanced-performance project (JET-EP) under the European Fusion Development Agreement (EFDA). Due to financial constraints it has recently been deci ...

Microfluidic chips for clinical and forensic analysis

This review gives an overview of developments in the field of microchip analysis for clinical diagnostic and forensic applications. The approach chosen to review the literature is different from that in most microchip reviews to date, in that the informati ...

A review with some new data. Adding a vibration on a laminar jet for controlled break-up into monodisperse microcapsules is one among different extrusion technologies for encapsulation of cells, microbes, yeast, enzymes and liqs. (Poncelet, 1997). The vibr ...

This paper analyzes by numerical simulation the formation, the fragmentation, and the penetration in a plate of a copper jet that develops in a shaped charge. A finite element Lagrangian code has been used to gain insight into this problem. The study is co ...

2002

A hybrid magnetohydrodynamic (M H D)-gyro-kinetic model CASTOR-K developed for the study of Alfven eigenmode (AE) stability in the presence of energetic ions has been applied to the interpretation of recent measurements of Alfven waves in JET. These includ ...

Characterisation and origin of arc fluctuations in a F4 DC plasma torch used for thermal spraying

Christoph Hollenstein

The fluctuating behaviour of a Sulzer Metco F4 DC plasma gun has been investigated. The time dependencies of the arc voltage and current and of the optical emission of the plasma jet have been measured. An optical fibre inside the gun allows direct measure ...

2001

Alfven eigenmodes and other magnetohydrodynamic phenomena have been studied in tokamak plasmas at the Joint European Torus (JET) using a new eight-channel, 4 s, 1 MHz, 12-bit data acquisition system (KC1F) in conjunction with the JET fast Mirnov magnetic f ...

Remote Handling Experiments with the MASCOT IV Servomanipulator at JET and Prospects of Enhancements

Ongoning remote handling trials are being performed at JET, using the MASCOT IV servomanipulator, in order to establish the feasibility of proposed remote handling tasks. This promotes the development of appropriate tools and methods, the determination of ...

Observations of Outflowing Jets

Some recent investigations on outflowing jets indicate an increased interest in phenomena studied for the first time some centuries ago. The highly spatial flow character and the beauty of jets issued by vertical, rectangular orifices are herein documented ...
