How can I solve this problem? ( Capacitor discharge, SCR, low coil resistance )

I want to discharge capacitor in micro seconds, In order to to that I used very low resistance coil but When capacitor is discharged,
SCR kinda blow up, meaning the positive & negative got connected together because of low resistance.
What can we place in negative terminal to make sure that positive & negative does not gets connected! ?
Since coil resistance is very low!
Like- Diode or something?

It is a very difficult operation.
Even without the SCR, discharging a capacitor with extremely low resistance is equivalent to shorting it. If the capacitor has a high capacity, this is equivalent to passing many amps. The capacitor, in fact, has an extremely low output impedance. When you short-circuit a capacitor to discharge it in a few moments, sparks and bursts are created because the current in transit is too high.
How many microfarads is your capacitor?

I calculated inductance of coil by dividing total current by total time, in order to get current / mS. Is it right ?? ( V/L=Di/Dt )

Or I have to divide total current / mS ??
