  1. Overview of High Pulsed Power domain and their applications Dominique Huet - EGO

  2. ~min Initial Storage Inductive storage ~µs Capacitive storage Pulse forming section • Vacuum lines • Plasma Opening Switch • Water lines • Éclateurs ~100ns • Z-pinch • Short circuit • Diode Load Radiation High temperatures High Pressures Electron Beam Principles and applications of HPP • Marx generator • Inductive Voltage Adder

  3. 2MA, 800ns • 505kJ à 80kV • Ø=5m, h=7m • 4MA, 1µs • 1120kJ à 50kV • Ø=18m, h=3m • Ø wires: 10 to 50µm • Rpinch: cm • hpinch: cm Generators and Z-pinch

  4. Plasma Guns Plasma Anode Cathode CONDUCTION PHASE OPENING PHASE The POS Load Amplifier Generator Diffusion equation in the framework of the MHD • The diffusion term installs a precursor field from which the 2 others effects can exist • Problem when it happens on lengths smaller than those defining the validity of the MHD
