In tokamaks and stellarators, measurements of electromagnetic fluctuations in the presence of resonant particle drive, including fusion-produced alpha's, reveal the excitation of Alfven eigenmodes (AE), related under certain conditions to a degradation in ...
The TCV Tokamak was designed to create a large variety of plasma shapes. Such a large flexibility requires high precision magnetic measurements with a good spatial coverage. This article gives a detailed description of the magnetic sensor geometry, fabrica ...
Detailed electron density profiles of the scrape-off layer in high-performance JET plasmas (plasma current, I-p < 5 MA, neutral beam heating power, P-nbi similar to 17 MW) have been measured by means of a lithium beam diagnostic system featuring high spati ...
Ballooning theory is an asymptotic method for treating modes with short wavelength across the magnetic field lines but essentially no phase variation along the lines. The latter constraint leads to problems with maintaining the physically required poloidal ...
Alfven waves in fusion plasmas play an important role in a number of situations. First, in Alfven Wave Heating (AWH) schemes. Second, both theory and experiment have demonstrated the existence of Global Alfven Eigenmodes (GAEs). GAEs have been observed in ...
This paper presents an overview of results of the 1994/95 experimental campaign on JET with the new pumped divertor and draws implications for ITER in the areas of detached and radiative divertor plasmas, the use of beryllium as a divertor target the mater ...
A method of obtaining a relative calibration of Si photodiodes for the spectral range of soft x rays (1-30 KeV) is presented. A simple mathematical model of the p-n diode is adopted which allows the response to be described in terms of a small set of param ...
