EXPERIMENTAL INVESTIGATIONS OF PUMPLESS TRANSVERSE-WAVE AMPLIFIERS,
Abstract
The unexpected gain of the drift-tube amplifier has been reproduced in new experiments. Three tubes demonstrated the correlation between net gain and sidewise gun displacement. No correlation existed between net gain and drift-tube diameter, which is contrary to the beam image pumping hypothesis. The net gain was in excess of 20 db, but the efficiency was poor. A tentative explanation of the gain mechanism is based upon the proposition that transverse waves were excited in the injection process, and that their rotational power was transferred to the beam wave excited by the RF signal.
