How to understand theSRIM results

Hi,
Thanks a lot for your reply.
Finally we will get the drift lines like below and it seems like the function of TrackHeed, while the TrackHeed is for the high energy particle,but the TRIM for the low energy particle, is that right?

Yes, TrackHeed is normally used for relativistic charged particles (“mips”), TrackSrim and TrackTrim are used for highly-ionising particles like ions slowing down in the gas.

Hi,
Thanks a lot for your reply
I understand it now
