Argon-photoion-Auger-electron coincidence measurements following K-shell excitation by synchrotron radiation.

Nonequilibrium electron rings for synchrotron radiation production.

Electron storage rings used for the production of synchrotron radiation (SR) have an output photon brightness that is limited by the equilibrium beam emittance. By using interleaved injection and ejection of bunches from a source with repetition rate greater than 1 kHz, we show that it is practicable to overcome this limit in rings of energy ∼1  GeV. Sufficiently short kicker pulse lengths enab...

Synchrotron Radiation and Pretzeled Orbits Geometry of Synchrotron Radiation Illumination

Turning on a `pretzel' , or any closed orbit distortion, can substantially alter the path of synchrotron radiation (SR), in some instances causing it to strike components not designed to absorb the radiation. In this paper I develop equations useful in determining the source position and angle of dipole SR as a function of the pretzel amplitude and angle. Formula for linear power deposition and...

Measurement of synchrotron-radiation-excited Kossel patterns.

Kossel line patterns contain information on the crystalline structure, such as the magnitude and the phase of Bragg reflections. For technical reasons, most of these patterns are obtained using electron beam excitation, which leads to surface sensitivity that limits the spatial extent of the structural information. To obtain the atomic structure in bulk volumes, X-rays should be used as the exc...

Electroweak Synchrotron Radiation*

We calculate the emission rate and spectrum for radiation of neutral electroweak bosons (Z”) f rom an electron in a weak external homogeneous electromagnetic field satisfying 1 f Fcly Fp”/1/2 < Fc 3 mzc3/eti. The calculational method is based on the source theory formulation of quantum field theory introduced by Schwinger. In particular for ultra-relativistic electrons, we find that the 2’ emis...
