Abstract :
CPD cathode, made out of tungsten wire, using active sintering resulted in uniform and two-fold emission as compared to B-type cathode. Studies on wire diameter using MATLAB code suggests that 20 μm diameter provides optimum barium coverage. Detailed experimental results will be presented.
