Cut plane function for AC/DC/charged particle tracing

Please login with a confirmed email address before reporting spam

Hi, I am using the charged particle tracing module from the AC/DC module to simulate an Einzel lens. To get the beam shape i want to have the x and y positions of all my particles for several z values (propagation direction). When i export all data the particles are sorted after time, but do not feature the same z coordinates. I tried to do it with "cut plane", but that didnt work out. How could I do that? I would be very grateful for any help!

Have you considered using plotting particles on the cut plane using a Poincaré map plot?

  • Add a 3D plot group.

  • Add a Poincaré map plot to the plot group.

  • Set Cut plane=Cut Plane 1.

  • Plot: This shows the intersections between the trajectories and the plane.

  • Results > Export: Add a Plot export node.

  • Set Plot group=the 3D plot group created above.
