Abstract: Results of calculation and measurements of traveling wave tube (TWT) characteristics with sections of  non-synchronous interaction intended  to reduce phase sensitivity of the device to a change of electron beam voltage are given. Calculated and experimental data are compared; reasons of their discrepancy and possibilities of further improvements of TWT parameters are discussed.

Keywords: phase-stable TWT; crestatron section; suppression section; phase sensitivity.
