Abstract
Emission of whistler waves by a density modulated electron beam is stu died in a laboratory plasma and compared to excitation by loop antenna . Single and double pole excitation are predicted by a simple linear m odel which agrees with the experiments. The fraction of the power of t he modulated beam radiated by the whistler wave has been measured and is of the order of 10(-5).
