Abstract
AN experimental investigation of the principles of microwave klystrons is rendered difficult by the inherently high operating frequencies at which it is not feasible to measure such quantities as input and output voltages. An important parameter in the klystron is the length of the drift space. In the normal operating range this is usually less than 1 cm. It is therefore difficult to carry out quantitative experiments in which the drift-length is varied. The drift-length depends on the transit time of the electrons and its relation to the high-frequency period. Thus lowering the operating frequency gives longer drift-lengths. Cullen and Stephenson constructed a special demountable klystron to operate at a frequency of 300 Mc/s, in which the optimum drift-length was about 5 cm and it was fairly easy to investigate the effect on performance of varying this length. Voltage measurement at 300 Mc/s still presented some problems.
