Source Properties of a Hollow Cathode Arc Plasma
Experiments have been carried out on the properties of a hollow cathode as an ion-source. The measured electron density, ion and neutral temperatures and drift velocities have been compared with predictions from the conservation laws for matter, momentum and energy. Very large exit drift velocities of ions and neutrals are observed. The magnitude and direction, against the electric field, can b...
متن کاملLaser Power Noise Measurements on a Cataphoretic He - Cd + Laser
Power output fluctuations at frequencies in the kHz to MHz range are commonly observed in gas lasers. In case of the cataphoretic He-Cd laser violent fluctuations of the order 50% peak to peak can occur [1]. This noise appears to be different in nature from e.g. He-Ne laser noise [2]. Its origin was attributed to neutral cadmium vapor density fluctuations [3] and to the coupling of Penning elec...
متن کاملA high - current hollow cathode as a source of intense line radiation in the vuv
The vuv line emission of a high-current DC hollow cathode was investigated in the wavelength region 10 nm to 100 nm. Spectra of quadruply ionised atoms could be observed. The radiance in the AI IV lines at 13 nm and 16 nm and in the He I1 Lyman-series was determined by a comparison with the spectral concentration of radiant intensity of the synchrotron radiation emitted by the electron storage ...
متن کاملHigh current hollow cathode as a radiometric transfer standard source for the extreme vacuum ultraviolet.
A high current hollow cathode source has been developed as a radiometric source standard for the extreme VUV. The source is operated at a constant current of 2 A with an aluminum cathode and helium or argon as buffer gas at pressures of ~1 hPa. The radiance of spectral lines in the wavelength range from 13 to 60 nm has been determined by comparison to the calculable spectral radiant power of th...
متن کاملPulsed-laser micropatterned quantum-dot array for white light source
In this study, a novel photoluminescent quantum dots device with laser-processed microscale patterns has been demonstrated to be used as a white light emitting source. The pulsed laser ablation technique was employed to directly fabricate microscale square holes with nano-ripple structures onto the sapphire substrate of a flip-chip blue light-emitting diode, confining sprayed quantum dots into ...
