WebThe visible and near-IR parts of the spectrum are dominated by the bremsstrahlung continuum which results from the scattering of plasma electrons by nitrogen molecules. The electron density and the reduced field E/N can be determined from the bremsstrahlung continuum by fitting the theory to experiment. WebBremsstrahlung, German for 'braking radiation', is the continuum emission created by the interaction of two "free" charged particles. Since unlike radiative or dielectronic recombination the interacting particle begins and ends the process without being 'bound', bremsstrahlung is often called 'free-free' radiation.

WebFree-Free or Bremsstrahlung Radiation Electrons in a plasma are accelerated by encounters with massive ions. This is the dominant continuum emission mechanism in ther-mal plasmas. An important coolant for plasmas at high temperature Examples : Radio emission from HII regions Radio emission from ionised winds and jets The continuous spectrum is due to bremsstrahlung, while the sharp peaks are characteristic X-rays associated with the atoms in the target. For this reason, bremsstrahlung in this context is also called continuous X-rays. The shape of this continuum spectrum is approximately described by Kramers' law.
