The electron beam is in continuous closed loop never colliding with anything. The energy
Transfer is between the electron linear accelerator to the electron beam where passing through the collimator by decelerating the beam expels radiant energy in the direction of linear travel. The electrons separate out in closed loop. The beam released passing through a concave glass lens striking a gas in the cone section. The beam is quite intense so then the gas temperature rise is instant to plasma temperatures. It’s a plasma motor. The beam intensity surpasses the sun surface luminous intensity. How do I know this? Collimator so already exist to create intense x Ray beams. Not science fiction.
