So you'll need a bandwidth of a few MHz to get decent 1MHz pulses. You reall y need to know the capacitance you're driving. Then you can experiment with the pulser driving a dummy load and get it right before touching the klystron.
Using an RF power valve is a good idea, but that's a very old design. If I wanted to get a pulser working quickly I'd do it with a FET. By SMPS standards this is not a demanding role. If I had to use valves I'd probably start with a TV line output valve such as the PL81 or PL36. Plenty of them around and they are rugged.
The other thing that would be very useful is a bench HT PSU.
