Safety requirements:
Electrical safety
- The anode, which is made of stainless steel, shall be isolated from the tube, in order to prevent the voltage from extending and crossing the tube.
- All the electric connection shall be coated by the right isolated according to the current and the voltage passing through the connections.
- The cables and connections of 9V shall be isolated with...

- The cables and connections of 21.7 V shall be isolated with...
Radiational safety
- For protection against X-Rays, a metal box with a lead plate inside shall be placed at the point of X-Rays emission.
Chemical safety
- Lead shall be completely enclosed to ensure that no toxic gases are emitted from it.
