How do I charge a capacitor with a battery?

I am trying to make an EMP for a robotics project. I have connected two 500 v capacitors in series to provide 1000 volts instantaneously. I know that the circuit in a disposable camera is able to charge the flash capacitor using only a 1.5 volt AA battery. I don't have access to a disposable camera but I need... show more I am trying to make an EMP for a robotics project.

I know that the circuit in a disposable camera is able to charge the flash capacitor using only a 1.5 volt AA battery. I don't have access to a disposable camera but I need to create a circuit that will allow me to charge my 2 capacitors to maximum capacity using only a 9v battery. how would I create such a circuit?
