This new coilgun model is made of 1 coil, yet I am using 2 stages of different polarities. The projectile is a magnet .25 in diameter by .25 in legnth. I am using a expensive optocouple with an off/on time of 20ns, for triggering the reverse polarity of the coil using the second stage capacitors by a second 1kv SCR.
