Topic: Plasma lamp

	Plasma lamp - Wikipedia, the free encyclopedia
		Plasma lamps (also variously "plasma globes", "plasma balls", "plasma domes", "plasma spheres"', or "plasma orbs") are novelty items which were most popular in the 1980s.
		The plasma lamp was "discovered" in 1904 by Nikola Tesla after his experimention with high frequency currents in an evacuated glass tube for the purpose of studying high voltage phenomena.
		Plasma lamps are mainly used as curiosities or toys for their unique lighting effects and the 'tricks' that can be performed on them by moving the hands around them.

	Plasma (physics) - Wikipedia, the free encyclopedia
		The dynamics of plasmas interacting with external and self-generated magnetic fields are studied in the academic discipline of magnetohydrodynamics.
		While electric fields in plasmas are usually small due to the high conductivity, the electric field associated with a plasma moving in a magntic field is not affected by Debye shielding.
		For many purposes the electric field in a plasma may be treated as zero, although when current flows the voltage drop, though small, is finite, and density gradients are usually associated with an electric field according to the Boltzmann relation.

		Plasma lamps also conventionally require a separate mechanism to couple the radio wave radiation generated by the radiation source to the bulb filled with the plasma discharge-forming medium.
		Figure 3 is a side cross-sectional view of a plasma lamp according to a third embodiment of the invention in which the gas housing is integral with a waveguide comprising a solid dielectric material.
		When the plasma lamp is constructed in such a way, the heat produced by the bulb operated in the normal drive mode will be dissipated more uniformly and rapidly than in the prior art because of the tight fit between the quartz bulb and the surrounding ceramic.

		lamps, a RF source provides RF energy at a certain frequency to a lamp head, the lamp head being part of a separate resonant circuit which is designed to resonate at the frequency of the provided energy.
		The continuous change of the plasma's resistance and inductance changes the resonant frequency, since the resistance and inductance of the plasma are reflected back into the primary or driving circuit for the lamp head.
		The lamp with the omega configuration coil was preset to 26 volts and, with assisted starting, when switched on came to near 2700 lux in 7.5 seconds without additional intervention.

	The Fluorescent Lamp: a plasma you can use
		The resistance of your fluorescent lamp is not fixed, it depends on the current carried: the greater the current, the smaller the resistance.
		The mercury atoms in the plasma generate light very efficiently, but much of it is ultra-violet (UV), invisible to the eye and harmful to it (or rather, it would be, were it not absorbed by the glass).
		If a fluorescent lamp were not protected by a ballast, it could in principle draw a huge current.

	High-Density-Infrared Transient Liquid Coatings
		Another feature of the plasma lamp for this facility is a water window (Figure D), which passes a thin film of water over the quartz glass covering the elliptical reflector to protect the lamp when operating in harsh environments.
		The lamp is typically configured with a reflector to produce a line focus or an area of uniform irradiance (Figures 3a and 3b).
		Plasma spraying is a long-established coating process in which powder particles of the coating material are melted in gas plasma and propelled onto the substrate surface.

	Plasma — Infrared Processing — An Introduction
		The lamp is sealed at the ends in which the cathode and anode are located.
		The plasma is stable and produces a radiant spectrum of 0.2-1.4μm.
		The spectrum is primarily in the infrared (0.78-1.00µm), although substantial energy is released in the visible wavelength, similar to the appearance of natural sunlight in energy distribution and colour rendition.

	Plasma ball, controlled electrical storm.
		Plasmas consist of freely moving charged particles formed when electrons are stripped from neutral atoms.
		In this lamp, the electrical discharges create localized plasmas that we can see by the glow of the recombining atoms.
		Since we are 'good conductors to ground' from the plasma's point of view, the plasma discharge is drawn to your hand when it is near the lamp and will follow as you move around its globe.

		Plasma is sometimes called "the fourth state of matter", beyond the familiar three--solid, liquid and gas.
		Plasma physics is a difficult, mathematical field, whose study requires a thorough understanding of electromagnetic theory.
		Meanwhile in the 1950s efforts began to confine plasma in laboratory magnetic fields for producing controlled nuclear fusion, and in the process the theory of trapped particles was greatly developed and expanded.

	ORNL, Vortek have solution to surface processing needs
		With the Vortek plasma lamp and ORNL’s materials expertise, coatings can be applied 10 times faster than with conventional techniques with no degradation of the wear-resistant coating.
		The Vortek plasma lamp produces the same power density as the high-powered industrial lasers that Native American Technologies has been using for thermal forming, but over a much larger area.
		The radiant plasma source offers far greater speed and temperature control than is possible with the tungsten halogen lamps widely used in the semiconductor processing industry.

		The lamp could not be quickly turned on and off: It took 10 seconds from turning on the switch to the time a useful amount of light was put out, and another 5 to 10 seconds before the lamp had achieved full brightness.
		CatEye eventually took this lamp off the market, and is about to introduce a new version of it that addresses some of the problems of the earlier unit.
		The system includes a 12 watt ordinary incandescent (halogen) lamp which automatically goes on when the plasma lamp is first fired up, and goes out when the plasma lamp reaches adequate brightness.

	AG Talk 2003
		In this talk we will hear a brief summary of one method of frequency exposure; the modulated plasma lamp, using both commercial and home-built equipment. In use, one simply has to be near the device while its running.
		Two controls, not exposed to the plasma, were also prepared, incubated and measured at the same times as the exposed samples. E.coli multiply in about 20 minutes, and provide the typical growth curves you see here.
		When a plasma lamp is exposed to energy, it doesn’t just “turn on”, but instead follows a different mechanism.

	Powerful Lamp Destroys Anthrax Better Than Foam
		Up to 10% of the ORNL's 300,000-watt lamp is in the ultraviolet spectrum, making it far more lethal to bacteria than lower-powered mercury vapor and xenon lamps currently in use.
		The researchers also believe the plasma arc lamp can be used to neutralize chemical warfare agents.The process would involve spraying the area with a low-volume proprietary mixture of harmless chemicals and then zapping the area with the lamp.
		The lamp was used to metallurgically bond a metallic coating to a metal substrate to demonstrate that barrel materials can be made more resistant to these forces.
