Muon Chambers: mass production at PNPI is successfully completed in the middle of 2006

all the chambers are already stored at CERN

Estimated total counting rate is approximately 1500 events per day

J/Ψ production acceptance, AliRoot estimation.

The peak at 0 pseudo-rapidity corresponds to the case when both muons are detected in ALICE barrel,the middle 1 muon is detected by the barrel, another one hit the dimuon spectrometer, the third peak is formed by the muon pair detected by the dimuon arm.
