Decreasing Capacitor charge time

[poekrel]

im working on a project that is using a parallel capacitor bank made of four 400V 6300uf caps. I am going to use a 120V outlet as the power source and my problem and question are this: as it is, according to pspice, it will take roughly forever for the bank to reach its 400V from the CW multiplier circuit i made. is there any ways to significantly reduce the time to get fully charge or perhaps a different method for stepping up the voltage i could use?

Since I now see that the application is a coil gun, this thread is closed. We do not discuss dangerous actitivies here on the PF.
