Look for EG&G application notes on series triggering.  You may find the
stuff in the Perkin Elmer website.

In particular, search for datasheet T4000E-3

There's a variety of series injection trigger transformers:
TS-136B is the biggest.. 4.8mH unsaturated, 110uH saturated secondary L,
0.02 ohms, 30:1 turns ratio, 1usec pulse width
TS-179 looks like the smallest... 15kV out, 25:1, 3.8mH/80uH, 0.05 ohms, 12
A RMS
The back page (of 4) in the datahseet has sample schematics.

Get yourself a copy of Edgerton's book, before you fool around much more.
Much useful information there, and it will save you a bunch o'bucks in the
long run.
