WebOn which principle does klystron tube operate? The two-cavity klystron is a widely used microwave amplifier operated by the principles of velocity and density modulation . An electronic oscillator can also be made from a klystron tube when the second cavity resonator is fed back to the first one with a coaxial cable or waveguide. Webcavity klystron amplifier and derive the bunching parameter. (8) b) A reflex klystron operates under the following conditions: V o =500V, R sh =10KΩ, f r = 8 GHz, L =1 mm, e/m = l.759 x 10 11 (MKS system) The tube is oscillating at f r at the peak of the n = 2 or mode. Assume that the transit time through the gap and beam loading to be neglected. WebThe klystron amplifier (6GHz) capable of sweeping the frequency was used. The incidence/reflection of microwave power were detected with directional coupler. The iris and plunger were controlled during sample heating so that the cavity always becomes resonant state. These operations were controlled with personal computer. e and s family medicine portal
