Particle Tracing: Magnetic Lens Simulation

[@hpsmith2010]

When you were choosing forces, why did you only need to choose "magnetic force"? IOW why did you not need to also choose particle-particle interaction to account for space charge (i.e. repulsion between like charges)? Or does the software do that automatically?

This is very useful and well done! How about an electron beam with a static electric field using the latest and greatest version of COMSOL?

Where can I find the tutorial to model the coil? Thanks in advance

[@evolivid]

can you make a positron coil too!!! wow

[@wildwoofer3147]

how can I plot the magnetic field?

[@Spix_Weltschmerz-Pucket]

Awesome stuff! Thanks!

Where we find the existing magnetic file

[@bestof1808]

is it electrospray?

[@ytu9378]

Thanks for the video! What if I can not choose a cut plane when setting the Poincare plot?

[@ytu9378]

I mean, there are only two options: None, or From Parent. The cut plane 1 (xy plane, z=0) I created in the Dataset is not an option.

[@ytu9378]

Hah, I got it. The method is: you choose "particle 1" as its dataset when building the cut plane.

Is there anyway i can get this file that you have?

Hi Rob, you can download the model file from this page: www.comsol.com/model/magnetic-lens-10185
