Cylindrical condenser

In order to obtain an insight into the intramolecular energy losses of photo-ejected electrons, their kinetic energy distributions have been measured by the method of the retarding field in a cylindrical condenser, schematically shown in Figure 8, for a sequence of monochromatic wave-... 

Fig. 8. Cross section of the cylindrical condenser for measurements of the kinetic energies of the photoelectrons from gas molecules. 1—fluorescent layer for intensity measurements of the incident light 2—thick metallic cylinder with wrought semi-annular slits 3—Teflon insulator 4—cylindrical grid 5—electron collector 6—LiF window 7—diaphragm 8—shutter 9—exit slit of the vacuum monochromator.

The projectile beam was monitored with a separate detector, also having an RFA for diagnostics. The system of Schmitt et al. (1994) was similar, except that the scattered positrons or ejected electrons were monitored using a rotatable 90° cylindrical condenser spectrometer. 

Suppose a radial electrostatic field is produced by a cylindrical condenser. The trajectory is then circular and the velocity is constantly perpendicular to the field. Thus the centrifugal... 

Besides a magnetic field, an electric sector field also influences the trajectory of the ions. An electric sector field analyzer as a section of the cylindrical condenser consists of two cylindrical... 

Many types of electron energy filter or analyser exist. Perhaps the commonest is the hemispherical condenser although a commonly used commercial instrument is based upon the 127° cylindrical condenser. ... 

Figure 1. High resolution Bragg spectra at A = 3.1 /urn-1. Excitation fraction P(ut) as a function of the excitation frequency uj/2-k. Open and closed circles same measurement at different Bragg laser intensities. A splitting in the spectrum is clearly observed at both intensities. Expansion of the excitation state in a Bogoli-ubov mode basis of an infinite cylindrical condensate, gives good agreement with these measured resonances, and characterizes them as radial Bogoliubov modes.

Rotating condenser columns, of which the column wall is heated and in which a cylindrical condenser revolves (Fig. 283) ... 

The static dielectric constant has been measured with a conventional dipolemeter DM 01 (WTW) working at 2MHz with a vertical cylindrical condenser especially designed to allow a great temperature stability (better than 0.03 C) and correct determination in situ of the temperature of the solution using either a thermocoax calibrated to 0.05 C or a conventional mercury thermometer. The estimated accuracy is 0.5%. 

Pictures of the chamber are taken by a camera fitted with two lenses so that stereo views of the tracks appear on the same piece of 35 mm film. Light is provided for dark field illumination by a flash tube on the opposite side of the chamber with the light passing through a cylindrical condensing lens before striking the chamber. 

As indicated by Figure 9.9, this column has a horizontal condenser and vertical, cylindrical condensate receiver or reflux drum. We will assume that the level controller is of the PI type with set point at midscale of the level transmitter span and that gain 2 auto overrides are employed. Hie level overrides then function as described in the following. 

Recent experimental investigations demonstrate the possibility of external perturbation and control of spiral waves in the BZ system [54-60]. For this purpose, Perez-Munuzuri et al. [57] applied a dc current to a shallow layer of the medium with a cylindrical condensator. A small (needle-shaped) electrode was placed over the spiral tip which increased the core size by slowly attracting the inhibitory bromide ions. Thus, the period of spiral rotation was increased with the applied voltage.
