A reflex electron beam glow discharge has been used as a plasma source for the generation of broad-area electron beams. An electron current of 120 A ( 12 A/cm2) was extracted from the plasma in 10 ps pulses and accelerated to energies greater than 1 keV in the gap between two grids. The scaling of the scheme for the generation of multikiloamp high-energy electron beams is discussed. E HAVE demo...

The dynamics of a nanosecond discharge with an extended hollow cathode in argon is studied and the electron energy distribution function (EEDF) plasma column calculated. issues formation EEDF inside cavity are considered. conditions validity two-term approximation analyzed appropriate evaluations given. Keywords: cathode, pulse discharge, argon, function.

This chapter presents transmittance scaling; a technique aimed at conserving power in a transmissive TFT-LCD with a cold cathode fluorescent lamp (CCFL) backlight by reducing the backlight illumination while compensating for the luminance loss. This goal is accomplished by adjusting the transmittance function of the TFT-LCD panel while meeting an upper bound on a contrast distortion metric. Exp...

Color gamut and static and dynamic color shifts of a multi-domain in-plane-switching liquid crystal display (IPS LCD) are calculated quantitatively using RGB (red, green, and blue) light-emitting diodes (LEDs) and cold-cathode fluorescent lamp (CCFL) backlights. Simulation results indicate that the LED backlight exhibits a wider color gamut, better angular color uniformity, and 2-4X smaller sta...

There are several types of dimmers generally available. Those employing triac or thyristor devices operate in a very similar fashion. These are used for resistive, and inductive loads, such as incandescent, cold cathode and low voltage (inductive) lamp sources. Note that not all electronic transformers used for low voltage lamps are suitable for dimming by triac or thyristor dimmers. Specialist...
