Abstract :
Experiments on the resistive-wall instability have been conducted. Electron beams with energies of 2.5 to 8.5 keV and currents of 30 to 135 mA are transported through a resistive glass tube for this experiment. The resistive tube is one-meter long and the resistance is 5.4 kΩ. The electron beams in the resistive tube are uniformly focused by a long solenoid. Localized space-charge waves are generated in the beams to investigate any energy spread change as a result of the resistive-wall instability. A longitudinal energy spread of the space-charge waves is measured at the entrance and the exit of the resistive channel for comparison. The preliminary experimental results are presented
