PCSS low jitter trigger can reach 65 ps in the condition of high bias electric under the non-liner mode [1-5]; high power transient pulse can be gained by virtue of it. The high power transient pulse in-phase characteristic and other tenets are verified by testing axial electric field strength and axial energy density, which is energy per area at the antenna main radiation direction. In the experiment, axial electric field strength and energy density of antenna array measured in different conditions indicate that axial electric field strength is proportional to the number of antenna elements and the energy density is proportional to the square of the number of radiation units, which means the transient electromagnetic pulses could synthesize in phase perfectly.

This paper describes the development of a small field-distortion spark gap switch. Comprehensive experimental studies made with the switch revealed its self-breakdown characteristics, voltage operating range, time delay and jitter, repetition frequency and finally the electrode erosion processes and duration of its service life time. A series of design improvements were required to be implemented in the switch design. For example, to reduce the structural inductance of the switch and to improve its working characteristics, the main electrode was designed as a circular track structure. Similarly, to increase the operation stability and reduce the self-breakdown probability, the trigger electrode was designed as a disk-like structure. Moreover, to balance the gas pressure in the discharge region and increase the stability during closure, a circular hole was added at the center of the trigger electrode. The compact switch has a small size of only 150 mm × 42 mm, a weight of 1.5 kg and can successfully be operated at a voltage over 110 kV, at a repetition rate between 1 Hz to 50 Hz and having a jitter of less than 4 ns. It was experimentally demonstrated that during normal operation conditions, the switch life time exceeds 100,000 shots.

“…Although coaxial pulsed power apparatuses are widespread, researches on discharge characteristic over transformer oil/solid interfaces under nanosecond pulsed coaxial field, as opposed to discharge characteristic over gas/solid or vacuum/solid interfaces under uniform field, are less, which can't meet the rapid development of pulsed power technology [1][2][3][4][5][6][7]. Surface flashover, whether applied dc, ac or impulse voltages, are closely relevant to potential distribution gradient along interfaces between different dielectrics.…”
