What are the considerations for designing a capacitor bank?
Vary basic formula:
$$ u_L=\dfrac{di_L}{dt}$$ will give you 80V. But this is just inductor voltage not the supply and the rest of the circuit.

If you solve the right part of the circuit you will get a second order differential equation, damped or oscillating result. Now you need to make a whole circuit before asking just about bank capacitor. Not only the desired current slope is important, but also a current decay. You may find similar test setups like Marx generator, to get a whole idea. Marx generator
