LOW NOISE, LINEAR, VARIABLE GAIN, R.F. AMPLIFIER

Abstract

The first experimental results on a beam deflection model are given. On 35 different tests with changed models it was not possible to get the necessary current of the order of 20-25 ma through the deflection plates. The influence of beam density and initial velocity on the performance of deflection tubes is discussed and some general considerations are made on deflection tube systems. It is shown that, in the beginning, it is more reasonable to work with an uncompressed beam and with a larger cathode. In the 3-tube approach, it is shown that one can reach very good linearity with two tubes (pentodes or triodes) at low frequencies. The application of 2 or 3 different frequencies at the same time, however, shows no satisfactory performance. (Author)
