In this “discussion” you must not
only give some details about this component, but also how it basically works
and how it fits in with the LHC as a whole / what it is looking for (if
applicable). To provide a full answer to this you may also have to give a
little background on the physics that it is studying (i.e. dark matter,
Higgs boson, quark-gluon plasma etc).
It is essential that you include
pictures and write your response in YOUR WORDS. Do your best
to interpret the difficult physics into a manner that a general science
student could understand.
Realize that you can use more than
just this site. There are plenty of others out there which could help you in
this discussion.
