Application of the results of an investigation of propagation on a charge-free helix, conducted at the Research Laboratory of Electronics at M.I.T., has made possible the construction of traveling-wave amplifiers that have a higher stable gain than any of the earlier tubes constructed at that laboratory. The principal design changes include a reduction in the mean diameter of the helix and the use of a close-fitting glass tube for supporting the helix. numerous mechanical difficulties, primarily in connection with the alignment of tube parts, presented themselves. These were overcome well enough so that two tubes, having nearly the same performance were built.
