Can a ray gun be created? What would it fire? plasma? I know that the dimendion of the ray gun are too short for what am i going to say, but i want to ask if aside this problem this could work: I thought that maybe the things that you put in the ray gun to charge it are batteries, and that the raygun has inside a vacuum chamber wherr there is a coaxial capacitor, and the electric field is strong enough to break the dielectric, hydrogen pass trough this capacitor and it becomes plasma (like in the lightenings) it gets ionized, the potential difference between the capacitors is mantained by the battery, (in order to minimize it and get a strong enough electric field to break the dielectric we minimize the distance between the "plates" of the capacitor. ( V= E * d) ) then, passed the capacitor the protons are guided by a varying magnetic field in a circular path and accelerated by a "mini" cyclotron, then the beam gets fired.... but, how do we control the moment when to take the shoot? I mean after the cycle the proton gets out of the cyclotron, we cannot control when to fire the beam by a mechanism activated by the trigger right? There should be a way to keep the beam inside the ray gun till the trigger is pulled, how can this be done? Another question, once fired the beam would collide with the air, would it be deviated by the target? I guess this depends on the velocity of the beam but a little of deviation would be inevitable right? The light that is seen when the beam is fired is due to the air ionization, what colour is it going to be? Blue?
