摘要： Provided herein are a device and a method for determining the spin polarization of an electron beam where the device and method contemplate diffusely back-scattering the beam from an electron opaque target, at a kinetic energy less than 10,000 electron volts, collecting the scattered electrons which may be of a preselected energy range and within a predetermined solid angle relative to the target and the collector, and measuring the number of scattered electrons which were collected.

摘要： Mode converter for electromagnetic, light or infrared waves. This mode converter converts particle non-confining modes to particle confining modes. In a confining mode wave beam the phase of the wave with respect to time at a point of the beam having a given azimuth with respect to the beam axis is proportional to this azimuth. Two types of mode converter are disclosed. In the first type, the wave passes through a block of transparent isotropic material the thickness of which is proportional to the azimuth around the beam axis. In the second type, the converter is formed with triangular or sectoral plates of birefringent material and in each plate the slow and fast axes are given an adequate orientation.

摘要： 1488400 Separating isotopes JERSEYNUCLEAR - AVCO ISOTOPES Inc 27 Dec 1974 [27 Dec 1973] 55940/74 Heading H1D In an apparatus for separating isotopes, e.g. of uranium, by selective photo-ionization using laser radiation, the uranium is vaporized and flows in a sectoral path between plates 78 connected by fine wires 80, or separate coils having the same path, through which a current from a source 76 can be passed to give rise to a magnetic field 84 in alternate directions in adjacent chambers 66 which causes the ionized desired isotope to be deflected towards plates 78 for collection, the improvement consists in periodically reducing the magnetic field strength during the application of the ionizing radiation to reduce the Zeeman effect and increasing it immediately thereafter. The waveform of the source 76 is preferably a square wave with a dwell time at zero. At the ends of the chambers additional coils or thickening of the plates 78 is provided to properly direct the magnetic flux. The currents in the coils can be from 10,000 to 100,000 amps and the laser and field pulse repetition rate can be about 50 kHz. The plates 81 used for collecting the unwanted isotopes can be arranged to carry induced currents to contribute to the magnetic fields.
