Abstract : In a tube consisting of two Cuccia-couplers separated by a long metallic drift-tube, gain in excess of 30 db was observed. It was shown theoretically that the gain can be explained by a quadrupole pump field established in the drifttube by the beam itself, provided the dc-beam performs a spiralling motion close to the wall of the drift-tube. This is verified experimentally. (Author)
