4. Main directions of R&D for PPT
1. Production of max power in pulse.
2. Transfer to short pulses duration
(picoseconds, femtoseconds).

5. Main directions of R&D for PPT
It related to R&D of:
 new capacitor and induction energy storages;
 new switches.
Capacitors:
New materials: solid, liquid for receiving of max
electrical field.
Induction:
Superconductors: High Temperature
Superconductors.

Inductive energy storage: WM=B2/(2o) = (1-50)J/cm3
Capacitive storage: WE =.o.E2/2 = 0.01-0.08 J/cm3

7. Switch
Perspective directions are next:
1. Semiconductor Open Switches- using forming
of plasma in semiconductors, especially in SiC.
2. Vacuum switch with large cross section of
cathode plasma. Reduction of induction of
plasma channel (10-10 Henry).

Main task is low induction of switch channel.
