Abstract : Measurements on electron beams propagating in a gas-filled drift tube show pressure dependent longitudinally periodic variations of light intensity, microwave emission, beam head velocity and net current. These results are consistent with an ionization instability, such as that proposed by Eastlund. (Author)
