  • The Helmholtz coil shall be able to deflect the path of the electrons.
  • The target ( copper) shall be able to emit X-Rays after the electrons collide with it.
  • The detector shall be able to detect the X-rays.

 

 

Mechanical requirements:

  • The cathode shall be able to withstand the thermal and electrical Stress. 
  • The cathode shall be made of tungsten.
  • The anode shall be made of stainless steel.

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.
