Abstract
1. Широкополосная лампа бегущей волны (ЛБВ), содержащая замедляющую систему (ЗС) типа спираль с определенным шагом h, выходную секцию с поглотителем и экраном, имеющим продольно проводящие ребра, параллельные оси лампы, отличающаяся тем, что выходная секция вдоль оси лампы имеет участок длиной Lув, на котором зазор g между ребрами экрана и спиралью увеличивается плавно или ступенчато с не менее чем двумя скачками (ступеньками) от gмин до gмакс по направлению от начала к концу выходной секции. ! 2. Широкополосная лампа бегущей волны по п.1, отличающаяся тем, что на участке увеличения зазора между ребрами экрана и спиралью выходной секции происходит изменение шага спирали h. ! 3. Широкополосная лампа бегущей волны по п.1, отличающаяся тем, что длина участка, на котором зазор между ребрами экрана и спиралью увеличивается, удовлетворяет условию ! 0,2 Lч≤Lув≤Lч, ! где Lув - длина участка выходной секции, на котором происходит увеличение зазора между ребрами экрана и спиралью; ! Lч - длина чистого (свободного от поглотителя) участка выходной секции. ! 4. Широкополосная лампа бегущей волны по п.1, отличающаяся тем, что максимальная величина зазора между ребрами экрана и спиралью удовлетворяет условию ! gмакс≥2gмин. 1. A broadband traveling wave lamp (TWT) containing a retardation system (ZS) of the spiral type with a certain step h, an output section with an absorber and a screen having longitudinally conducting ribs parallel to the axis of the lamp, characterized in that the output section along the axis of the lamp has a section length Lu, in which the gap g between the edges of the screen and the spiral increases smoothly or stepwise with at least two jumps (steps) from gmin to gmax in the direction from the beginning to the end of the output section. ! 2. The broadband traveling wave lamp according to claim 1, characterized in that in the area of increasing the gap between the edges of the screen and the spiral of the output section, the pitch of the spiral h changes. ! 3. A wide-band traveling wave lamp according to claim 1, characterized in that the length of the section on which the gap between the edges of the screen and the spiral increases satisfies the condition! 0.2 Lh≤Luv≤Lh,! where Lu - the length of the section of the output section, on which there is an increase in the gap between the edges of the screen and the spiral; ! Lч is the length of the clean (absorber-free) section of the outlet section. ! 4. The broadband traveling wave lamp according to claim 1, characterized in that the maximum gap between the edges of the screen and the spiral satisfies the condition! gmax≥2gmin.
