Page 4-7 

  

Figure 4-5.

 The six M6-threaded holes are spaced according to this image (the electron gun/x-ray head seen 

from below). 

 

 

Mount the x-ray system controller and the x-ray high-voltage controller 

properly into a 19” rack 

located close to the electron gun/x-ray head and the pump box. 

 

Figure 4-6.

 Use the side br

ackets on the front of the pump box to attach the pump box to a 19” rack.
