That kind of rise time is usually done by using a Marx to charge a 
capacitor that then breaks down a "peaking gap".  Even a standard Marx with 
a peaking gap might work.  At those voltages, you'd probably want to use a 
pressurized gap to keep the physical size reasonable.

The current would be mostly determined by the stray L and C in the 
system.  You didn't mention a discharge energy, which is an essential 
design parameter.

Maxwell Labs (or Physics International), probably part of General Atomic, 
now, makes these sorts of things.
