Change: directions - like an apple! However as the energy of the electron beam increases the direction becomes spatially asymmetrical, projecting forward into a pear shape at 400keV, a cucumber shape at 4MV and a carrot aydirections. 20MV!The probability of bremsstrahlung production is View changes from previous version.

Change: The target stops the electrons and creates the opportunity for the production of x-rays. The target of rotating anode tubes is made of tungsten and rhenium alloy. Tungsten generally makes up 90% of the composition of the rotating target, with rhenium making up the other 10%. Rotating anodes View changes from previous version. (Word count: 401)
