Solid-state Marx bank modulator for the next linear collider

In this paper, we will discuss the design of a solid-state Marx bank modulator (Figure 1) for the NLC, which will deliver 150 ns risetime (10-90%) for a 500 kV, 530 A pulse (for two klystrons), with efficiency over 90%. The use of a common mode inductive charging system allows transfer of filament power without separate isolation transformers. The combination of these features supports future compact, inexpensive, very high voltage pulsed power systems
