The following might help, since the original author did not specify how
Joules are required from the flash these might just be a starting point.
These URL's might help:

For info on commercial stroboscopes (many frames per second):
http://www.unilux.com (highest power)
http://www.inotek.com (for Shimpo General Test, Pioneer, and Monarch)
http://omega.com (the HHT30)
http://www.checkline.com (their DT-721 and DT-725)

The first step I would take in designing/specifying a high power "flash"
would be to calculate the flash output required in Joules as flashes and
strobes are generally specified in those terms.

Dear Andrew,
Have you got instructions for building a fast (flash duration around
1/25000 s) high power flash e.g. f/45 at 1foot for 25 iso film.
Cheers, Peter.K.
