How to Change Electron Beam Pattern using LabView?

Hi, I am using LabView to control a Electron Beam furnace to melt metals. The current EB scanning pattern controlled by LabView is a circle as shown in the following figures.

 

 

I would like to change the current EB pattern to a circle with a gap. Electron beam needs to change direction continuously and move clockwise-anticlockwise-clockwise-anticlockwise-... I also would like to control the angle for the gap and its position. Does anyone know how to do this by LabView? I have been struggling with this problem for a while.I appreciate your time very much if you can help me in any way.

Hi Jason,

 

I also would like to control the angle for the gap and its position.

So all you need to do is to provide the corresponding XY cooridinates!

 

Does anyone know how to do this by LabView?

Well, yes: you need to calculate the needed XY coordinates!

For circle segments this is quite basic math involving some sin/cos calculations…

(As Christian probably would suggest too: using complex numbers may simplify your calculations also. :D)

Best regards,
