Abstract
The modes of FEL radiation propagating in a drift tube and their spati al growth rate were determined experimentally. A high growth rate of 6 0 dB/m was observed for the main mode (TE11 circular). Besides this, t he higher modes TE31, and TE51 were also detected. The spatial growth rates are 50 dB/m and 45 dB/m, respectively, and power saturation is o bserved at the same position for all modes.
