The equation V = i x t/C would be helpful here. Let's say you want a
break rate of 100 Hz. You have 10mS to charge the cap roughly.
Assuming the supply *is* constant current up to 15kV, you can find a
value of C that meets this requirement:
C = 10^-5 x 10^-2/1.5x10^4 Farads = 6.6pF not too good really.
Perhaps someone had better check my arithmetic.
