概要:

New diagnostic, "electron-beam-shadowgraph", is examined for taking the spatial distribution of transient fields in a plasma. It is applied to the unmagnetized plasma, which is perturbed by an intense relativistic electron beam (IREB). Strong deflection is observed with duration of about 1 μs just after the IREB injection. The shadowgraph image is characterized by presence of aggregate holes. The size of the hole is changed with the plasma density, and … corresponds to the 15 - 60 Debye lengths. Important agreements are observed between the experiment and the strong Langmuir turbulence theory. © 2002 AIP. 続きを見る
