The L-H transition in the ASDEX tokamak was investigated. The level of fluctuations both in the scrape-off layer and in a narrow region inside the separatrix drops on a 100 mu s timescale. Density turbulence coming from the edge and magnetic turbulen

Frequency shifts in the megahertz region, as required under certain conditions in far‐infrared diagnostics of magnetically confined fusion plasmas, can be achieved via multiple diffraction by a cylindrical diffraction grating rotating at moderate s

There exist two classes of discharges on ASDEX which overcome the severe confinement deterioration at high densities or heating power. The first class is characterized by unusually peaked density profiles and the second one by exceptionally broad one

In magnetically confined plasmas density fluctuations of apparently turbulent nature with broad spectra in wave number and frequency space are observed which are thought to be the cause for anomalous energy and particle transport across the confining

The properties of GaAs Schottky barrier diodes as video detectors and mixing elements were investigated in the frequency range from 0.8–2.5 THz. For the most sensitive diode, the video responsivity and system noise temperature were measured as a fu

Frequency modulation of 119 μm (2.5 THz) H2O laser radiation by optically induced gratings in Si is reported. The gratings were excited using two diode‐pumped, frequency‐tunable Nd:YAG lasers. Frequency shifts up to 15 MHz were generated. With 2

Boron nitride (BN) films were deposited on (001) faces of silicon (Si) using pulsed excimer laser ablation at 308 nm and 248 nm. The films were analyzed by Fourier-transform-infrared (FTIR) transmission spectroscopy, x-ray photoelectron-spectroscopy

An investigation of subnanosecond switching of 119-microm radiation achieved by irradiating high-resistivity silicon wafers with 1.7-ns, 337-nm pulses from a nitrogen laser is presented. The experimental results are compared with a one-dimensional nu
