Whoa there Eric! There are three ways to avoid radiating yourself.
1) Measure the distance from the top of the light barrel to the center of the mirror and then to the center of the screen in the cabinet. Mount the CRT in the light barrel on a table approximately that distance from your ceiling. If you are sitting very close to the light barrel, I'd suggest adding scrap sheet metal between you had the barrel. Don't forget to ground both the scrap metal and the barrel.
2) Mount the CRT in the light barrel and jury rig a mirror at a right angle to reflect the image off the wall. or operate the light barrel on its side and project directly on the wall. Determine distance by experimentation. Don't forget to put a metal shield on the mirror side of the barrel when operating this way.
3) Disable the voltage trippler. Remove the 2nd and 3rd 8016's and feed the HV directly from the plate cap of the second now-removed 8016, to a standard high voltage 50-53 degree 5 inch test CRT. You will probably have to shim the yoke. The test tube is close enough to the sweep angle of the 5TP4 to not cause a problem, and any X-ray generation will be minimal at this much
much lower HV.
