Particle Contamination. In assembling large, high voltage equipment such as coaxial lines, contamination by metal particles may occur which may decrease the dielectric strength under various conditions by 5 to 10-fold (44—45). Metal needles are the worst contaminants and electrostatic traps or adhesive areas have been designed to cope with them (46). 

Figure 7.3 shows the two-beam photon-force measurement system using a coaxial illumination photon force measurement system. Two microparticles dispersed in a liquid are optically trapped by two focused near-infrared beams ( 1 pm spot size) of a CW Nd YAG laser under an optical microscope (1064 nm, 1.2 MWcm , lOOX oil-immersion objective, NA = 1.4). The particles are positioned sufficiently far from the surface of a glass slide in order to neglect the interaction between the particles and the substrate. Green and red beams from a green LD laser (532 nm, 21 kWcm ) and a He-Ne laser (632.8 nm, 21 kW cm ) are introduced coaxially into the microscope and slightly focused onto each microparticle as an illumination light (the irradiated area was about 3 pm in diameter). The sizes of the illumination areas for the green and red beams are almost the same as the diameter of the microparticles (see Figure 7.4). The back scattered light from the surface of each microparticle is...

An entirely new principle of the ion-trap mass spectrometers is the Orbitrap with a coaxial inner spindle-shaped electrode in an outer barrel-like electrode. The peripheral injected ions move due to their electrostatic attraction to the inner electrode on orbits around and swing simultaneously along the electrode. The frequency of these harmonic oscillations is inversely proportional to the square root of mJz. The detected signals are induced by the frequency of these swings and resulted... 

Coaxial (or assimilation) traps utilize an adsorbing material drawn out to a fine fiber to provide as much surface area as possible. The various different materials available provide varying capabilities. For example, copper provides the best absorption capabilities (particularly to hydrocarbon oils), but is not very durable and needs to be replaced often. Stainless steel (particularly good for acid environments) and bronze will survive better in tougher environments, and activated alumina is great when organics or pump oils need to be trapped. Like molecular sieves, these traps work at room temperature. Unlike molecular sieves, not all can be baked out for regeneration and typically must be replaced with the old one discarded in an environmentally safe manner because it is likely to contain a variety of harmful materials. 

Coaxials can trap large particulates, but are not designed for this purpose. 

This entire assembly was used as a rabbit and irradiated in a reactor for 3 minutes. After the irradiation, the rubber cap sealing the recoil chamber was punctured with a double-walled hypodermic needle, and air containing the recoiled krypton fission products was drawn out through the coaxial outer annulus of the needle. The effluent gases were passed through a trap paoked with glass wool, cooled in a dry ice-... 

Thickwire, as the name suggests, is a thick, hefty, coaxial cable and can be expensive and difficult to work with. A thick coaxial cable is used because of its immunity to common levels of electrical noise, helping to ensure the integrity of network signals. The cable must not be cut to install new nodes rather nodes must be connected by drilling into the media with a device known appropriately as a "vampire trap". Nodes must be spaced exactly in increments of 2.5 m apart to prevent signals from interfering with one another. Due to this combination of assets and liabilities, thickwire is best suited for but not limited to backbone applications. 

A coaxial heated restrictor consisting of a syringe with a movable piston position controls the flow, or alternatively a small metal disk is pushed toward an orifice in order to regulate the flow rate. The former is suitable for collection in organic solvents, while the latter has been utilized for solid-phase trapping. 

Two types of CTs are studied at Los Alamos Spheromaks and Field Reversed Configurations (FRCs). Spheromaks, which contain both poloidal and toroidal field components, are produced by a magnetized coaxial source (magnetized Marshall gun), as shown in Fig. 1(a). The separated spheromak is trapped and confined in a metal flux conserver not shown in Fig. 1. Coaxial sources, 30 cm in diameter, have been used to form spheromaks in the CTX facility and its predecessor, the Prototype facility. ...

Orbitrap, which was introduced into the market in 2005, is a new type of mass analyser, operating by radially trapping ions about a central spindle electrode. An outer barrel-like electrode is coaxial with the inner spindle-like electrode and mass/ charge values are measured from the frequency of harmonic ion oscillations, along...
