Betatron oscillations in electron beams produced from 200 TW laser interactions

Betatron oscillations in electron beams produced from 200 TW laser interactions. Electrons accelerated in the plasma - “wiggle” due to tranverse electric field in the focal region - Betatron Oscillations. Electron density 1.1x10 19 cm -3. 200 MeV electrons. Emission angle ~ 10 degrees.

  1. Betatron oscillations in electron beams produced from 200 TW laser interactions Electrons accelerated in the plasma - “wiggle” due to tranverse electric field in the focal region - Betatron Oscillations Electron density 1.1x1019 cm-3 200 MeV electrons Emission angle ~ 10 degrees These are evident in simulations as well as in energy spectra of accelerated electron beams T.
