PLASMA PHYSICS: STUDY DATA FROM E.V. ROSTOMYAN AND COLLEAGUES UPDATE UNDERSTANDING OF PLASMA PHYSICS

Science Letter
August 26, 2008

According to recent research published in the journal Plasma Physics
and Controlled Fusion, "The development of conventional beam-plasma
instability in a system penetrated by short electron bunches is
considered."

"The fields induced by the bunches’ edges increase exponentially and
actually serve as initial perturbations for instability development,"
wrote E.V. Rostomyan and colleagues (see also Plasma Physics).

The researchers concluded: "It is shown that superposition of the field
induced by front and back edges results in a complicated configuration
that can affect various aspects of operation of devices for short-pulse
microwave generation, e. g. transient processes."

Rostomyan and colleagues published their study in Plasma Physics and
Controlled Fusion (Development of beam-plasma instability in systems
for short-pulse microwave generation. Plasma Physics and Controlled
Fusion, 2008;50(8):85019).
