Thomson Scattering in Magnetic Fields [PDF]
AbstractThe equation of transfer in Thomson scattering atmospheres with magnetic fields is solved using Monte Carlo methods. Two cases, a plane parallel atmosphere with a magnetic field perpendicular to the atmosphere, and a dipole star, are investigated.

Multichannel Thomson scattering apparatus
A Thomson scattering apparatus for measuring the electron temperature and density along a 90-cm diam of the PLT plasma has been built. A wide angle objective images the 3-mm x 900-mm ruby laser beam onto an image dissector which rearranges the 300:1 image to 20:1 forming the input slit of a spectrometer.

Oscillations in the spectrum of nonlinear Thomson-backscattered radiation
When an electron beam collides with a high-intensity laser beam, the spectrum of the nonlinear Thomson scattering in the backward direction shows strong oscillations like those in the spectrum of an optical klystron.

Polarimetric variations of binary stars. II. Numerical simulations for circular and eccentric binaries in Mie scattering envelopes [PDF]
We present numerical simulations of the periodic polarimetric variations produced by a binary star placed at the center of an empty spherical cavity inside a circumbinary ellipsoidal and optically thin envelope made of dust grains.

Scaling law for the photon spectral density in the nonlinear Thomson-Compton scattering
We derive a new scaling law for the photon spectral density in nonlinear Thomson/Compton scattering, extending the findings of Heinzl, Seipt, and Kämpfer [Phys. Rev. A 81, 022125 (2010)PLRAAN1050-294710.1103/PhysRevA.81.022125]. This allows one to easily

Triple grating polychromator for Thomson scattering [PDF]
A high rejection, high transmission, triple grating polychromator with crossed dispersion has been designed and constructed for Thomson scattering plasma diagnostics. Identical gratings, collimating, and field lenses were used for all three stages.
