High-gain free-electron-laser amplifier with warm plasma background: linear analysis

The linear free-electron laser (FEL) theory with plasma background is considered using the hybrid model in contrast with the fluid model to describe the FEL interaction with plasma proposed by Weng-Bing and Ya-Shen (1988) and Tripathi and Liu (1990). The basic dynamical equations for the FEL with wa...

Zusammenfassung:	The linear free-electron laser (FEL) theory with plasma background is considered using the hybrid model in contrast with the fluid model to describe the FEL interaction with plasma proposed by Weng-Bing and Ya-Shen (1988) and Tripathi and Liu (1990). The basic dynamical equations for the FEL with warm plasma background are derived for all ranges of plasma and beam densities with unspecified wiggler period number and strength. The linear behavior of the FEL is analyzed.< >
