Re: DIY X-Ray & Auto Jigger transmitter
The linacs I worked with produced 6Mv x-rays. All around the head was lead shielding to try and protect the semiconductors .It helped that the majority of the x rays went forward from the target so only back-scatter was present.
The board didn't fail in a spectacular manner but gradually stopped working correctly. One set of boards had to demultiplex and drive 40 motors to millimetric position. When new they worked perfectly but as they got damaged the complete bank of motors would start to drift with no command signal. We put this down to the darlington drivers becoming leaky.
The linac head tries to show the amount of electronics surrounding the head. The target for the x rays is just in front of the brown disc. The disc is a thin 'window' to allow electrons to pass if electron therapy is used.
