Casino 3.3.0.4 and SEs - continued

[amit]

Hi everyone,
I was thinking initially that I could see the SEs Casino (v3.3.0.4). At least on the visual level in the program itself, I understand that this is not the case

Question No. 1: Am I wrong?

Then, I saved the data into the .dat file, which shows many trajectories. Next to most of them I see "secondary electron". I am not sure, then, what this trajectory is. Is it the primary's trajectory and each of those labeled with "SE" means it created one?

Question No. 2: Am I correct in my understanding?

Finally, even if I see tons of "secondary electron" labels in the .dat file, the SE yield on the GUI shows zero. And so I am more perplexed.

Question No. 3: What do the different colors in the distribution plot of the electrons signify? This is not well documented.

Question No. 4: Why is the SE yield zero?

Thanks for your help.
Amit

you will see the secondary electrons in the simulation result trajectory display as long as the tracking SE in enabled, the blue trajectories are primary electrons, the red ones are backscattered electrons escaped out of surface, and you can see many short trajectories with green color along the primary trajectories, which are secondary electrons.

I could be wrong, but my understanding is that the SE yield only counts the SEs escaped out of the surface.
