Pulsed electric system components

One of the key components in the system is the mass spectrometer. Fragments are ionized by a VUV laser pulse between a pair of plane parallel-plate electrodes (6 x 14 cm). One of the plane electrodes has a slit of 1 x 10 cm, which is covered by a metal mesh. The slit is parallel to the VUV laser beam and is the entrance of the mass spectrometer. Ions are accelerated by a pulsed electric field present between the plane parallel-plate electrodes, and then pass through the slit before they enter the mass spectrometer. [Pg.171]

The heart is mediated by an electrical system that is easily disturbed by toxicants changing the timing, flow, and magnitude of the electrical pulses and thus interfering with the required pumping action. The activity of the heart is myogenic, i.e. the activity is initiated by the heart itself Various components of the heart, the sinoatrial (SA) node, atrioventricular (AV) node, and the Purkinje fibers are capable of pacemaker activity. Healthy atrial and ventricular tissue does not engage in pacemaker activity. The primary pacemaker is the SA node, but in diseased or affected states the secondary pacemakers take over. [Pg.493]

Terahertz (THz) spectroscopy systems utilize far-infrared radiation to extract molecular spectral information in an otherwise inaccessible region of the electromagnetic spectrum where various rotational, vibrational, and translational modes of molecules are located, 0.1-10 THz (Fig. 1). As the wavenumber range is narrowed, THz-radiation can yield more specific information about a particular chemical component within the system. Unlike most spectroscopic techniques, THz instrument measures the wave temporal electric field, which can be Fourier transformed to yield THz pulse amplitude and phase. This added capability allows precise... [Pg.285]

For a given duration of the photon pulse, the probability of raising the system to the bound component (2s2p) or to the scattering component (Isep), in the vicinity of E = Eq, depends on the magnitude of the electric dipole-coupled matrix elements, = x and = x . I point out that the orbitals (ls,2s) are obtained from fheir own state-specific pofenfial and, fherefore. [Pg.202]

Self-diffusion coefficients for all chemical components in microemulsions may be determined by NMR pulse gradient spin echo experiments as exemplified by Lindman and coworkers [55-57]. Self-diffusion coefficients for toluene, water, acrylamide, and AOT in this aqueous acrylamide-AOT-toluene system are illustrated in Fig. 12 as a function of (J [58]. The self-diffusion coefficients for water, acrylamide, and AOT exhibit breakpoints near, but below the percolation threshold, in the neighborhood of 1.2-1.3% acrylamide. This breakpoint corresponds to the onset of percolation in electrical conductivity illustrated in Fig. 6 at 0- The AOT diffusion coefficients run parallel to those for acrylamide, but are offset to lower values. [Pg.172]
