Yup. The metal anode is phosphor-coated. What’s more interesting: it’s using a standard “defection IC” to detect sync pulses and generate horizontal and vertical ramps but the focus and horizontal width change dynamically as the picture is scanned top-to-bottom to achieve keystone correction and maintain sharpness.
Oh is it hitting the screen from the front instead of the back?
Yeah, the screen is slanted and it’s hitting it from underneath
