Abstract :
We describe the design, construction and testing of a highly compact pulse forming line design which addresses a requirement for a compact pulse power source producing a trapezoidal output waveform up to 30kV into a load impedance of 12.5. The complete unit has width, depth and height of 48cmx34cmxl0cm and fits into a 19" rack together with capacitor charging power supply and control unit. The PFL is a charge line formed from two rows of rectangular ceramic blocks. The blocks are a low loss commercial grade ceramic produced by Morgan Matroc. EM design studies showed how the PFL can be folded to reduce the overall footprint. The charge line output switch is a mid-plane triggered spark gap. The trigger electrode is driven by a e2V pulse transformer which itself is driven by a power electronic unit. The output voltage pulse can be set to the range 20-30kV with a fixed pulse width of ~30ns.
