Parametric refregeration discussion and experimental verification of the removal of slow-wave noise

It was for some time believed that it is impossible to remove noise from the slow waves of an electron beam [1]. Since the operation of a large class of microwave amplifiers depends on the coupling of the negative energy slow wave to a circuit, this belief led to the statement of various minimum noise figure theorems [2]. As a result of these theorems, much effort has been expended on the development of amplifiers which use the fast beam waves [3]; these waves may, in principle, be stripped of all emission excited noise.
