Dynamical model for magnetic signal interpretation in relativistic-electron-beam: heated plasmas

A dynamical model is developed to infer the energy content of a relativistic-electron-beam--heated plasma column from global or local magnetic field measurements. Under this model, magnetic signals are interpreted in terms of the propagation of macroscopic magnetosonic waves, and differences in charcteristics such as beam duration, probe position, and pulse shape, etc., can be distinguished. This model applied to experimental regimes where the commonly used static model becomes invalid
