Abstract: The present disclosure includes an electron beam emitter, a roller for a web, circumferential radiation shielding, a reaction chamber, movement between open and closes positions, a depositor, baffles, inert gas dispenser, and other features. One example in the present disclosure is a web carrying roller for electron beam irradiation of the web on one side of that roller within a baffle-containing shielded area, while another side of that roller is outside of the shielded area, and near the two ends of the roller are arcuate tongue and groove barriers to x-radiation leakage from the shielded area. The baffle-containing shielded area has a series of voids separated by walls, rather than having the shielded area positioned close to the circumference of the cylinder along its length.
