Leaded glass view ports and add on lead glass disks are available. But it will cost about $100.00 more, so a standard viewport and a CCD camera is the least expensive alternative.

Pictures are worth a thousand words. Attached is my arrangement for all to consider.

1. I pointed my 3/4 inch diamter 2.75 conflat mounted, pyrex, window down at the concrete lab floor. (Part of physical placement design of the fusor, itself.) Thus, the x-rays blast down into the floor.
2. Small board camera is a common $40.00 color CCD type with 12 volts in and video out. Its lens is mashed into contact with the window and focused on the grid. A cylinder of copper surrounds the camera.
3. Under tha camera is a 1/2' thick disc of poured lead. This absorbs most of the x-radiation and scatters some as well. Scatter is not significant.
4. The camera's video output is run to a small common video monitor that I picked up at a hamfest for $25.00.

The first image shows the setup in operation with the video monitor placed right at the control panel for easy control and viewing purposes.
The second image is a close up of the camera assmebly.
