(A) APPJ length (a) and voltage signal (b) at the first negative pulse in the bunch with a duty cycle of \(\approx 8\)%. (B) APPJ length (a) and voltage signal (b) at the first positive pulse in the bunch. The horizontal dashed line shows the position of the tube orifice. The signals correspond to the images in Fig. 2.
