ok ive just ordered a high voltage module like in the pic below but i need to know if a mark generator can handle the voltage that comes out of it?

 

You wrote Mark generator, but did you mean "Marx generator"? If so the answer is yet, if you use the right design for the Marx generator.

Here is a 100 kV Marx generator:
