Abstract
The experimental results of radiated power and its spectral parameters as measured on the Israeli electrostatic accelerator tandem FEL (EA-F EL) are interpreted and numerically simulated. Two complementary simul ation codes, FEL3D and MALT1D show good agreement with experimental re sults. The FEL3D code (a non-linear three-dimensional 'amplifier' code , based on a coupled-mode approach), was employed for calculation of t he small-signal gain, extraction efficiency and saturation power, This code (FEL3D) allows one to simulate FEL operation of multiple transve rse modes at a single frequency taking into account space-charge effec ts. Multi-frequency simulation of the mode competition process was car ried out using the MALT1D code based on a space-time multi-longitudina l mode simulation of a FEL oscillator.
