The objective frequency band are from few mc to few kmc, and the pulse width is few micro second or less. That, it is very necessary to study on the oscillation build up characteristics of the oscillator, in order to analyse the working mechanism or to improve the faculty, on the point of pulse sender at these frequency band, especially in micro wave band. These necessity are emphasised because of the difficulties of voltage amplification and wave form observation. We have studied, as the first step, on the build up phenomena of a reflex klystron, that is used widely in micro wave region. The method of the measurements are based on the super regenerative principles, that the quenched characteristics of an oscillator can be used to analyse the build up characteristics such as build up time or pulse envelope etc. As the results, next conclusions can be induce : (1) it needs the more time for build up,as the mode is more higher.(2)the noise domain of quenched oscillation split in few branches likewise a Christmas Tree,and each branches have closely relations to the corresponding mode.(3)On the otherhand,these characteristics are useful in designing the super regenerative detector of micro-wave frequency used a reflex klystron., Article, 信州大學紀要 (2): 133-138(1952)}, pages = {133--138}, title = {反射型クライストロンの抑振特性}, volume = {2}, year = {1952} }
