Except that these caps may not be designed for fast, very high current 
discharges.

[Optimally ;-)  And yes, XRay filter caps aren't likely to be ultra-low
inductance pulse caps.  But I imagine that if you whack anything with
15kJ, somethings going to give.  A capacitance of 2uF seems a bit
large for a coil though, and the cable will have it's own, not
insubstantial, capacity to add as well.  SRR]
