You can see live event displays from ALICE here. Perhaps you can identify the different detectors in the event display from the description of the ALICE detector. And here’s an event display with our Time Projection Chamber in:
What you’re looking at is the charged particles we’ve seen in ALICE. I’d tell you roughly how many we see except that I’m afraid that some theorists in our field would mistake that for a measurement. (You know who you are!)
There’s more information about ALICE and more event displays here.
(ATLAS and CMS also have event displays.)
