Public Liquid-Argon Calorimeter Plots for 2008 Data

Remark

The paper on LAr Readiness summarizes the LAr results on 2008 data. If you want more plots on specific analyses, go to the other sections below...

Main results :

Drift Time vs eta in the Middle Layer EM http://carolina.web.cern.ch/carolina/TdriftvsEta_S2_EMCoverage_FormatApproved.gifMiddle (eps)

The drift times of electrons in the cells of the second layer of the calorimeter are uniform at the level of 1.3% in the barrel and 2.7% in the endcaps. This leads to an estimated contribution to the constant term of (0.29 +0.05/−0.04) % in the barrel and (0.54 +0.06/−0.04) % in the endcaps.

Drift Velocity vs eta in the Middle Layer EM , at 88.5 K and for an electric field of 1kV/mm, is found to be 4.61 0.07 mm/μs.
