8cm length & 16*10-4 cm radius
Event rate:
N = L x (pp) 109 interactions/s
Mostly soft (low pT) events
Interesting hard (high-pT) events are rare
very powerful detectors needed

CMS similarities
General purpose CMS designed with equivalent performance
as ATLAS while independent cross check is essential 43
