Paper Abstract

We investigated the instability of space-charge waves in SSL in the conditions of the schemes of generation based on the the generalized LSA scheme. We demonstrate that in general case the condition for space-charge instability depends on the wave vector of perturbation k. This effect can change conditions for the operation in generalized limited space-charge accumulation mode of Bloch oscillator.
