Lorentz Angle and Cluster Width Studies for the ATLAS SCT
2009 (English)Report (Other academic)
This paper presents studies and measurements of the Lorentz angle and cluster size for the ATLAS Semiconductor Tracker (SCT). The performance of the SCT detector has been studied with cosmic rays during the commissioning period in 2008. The Lorentz angle and the cluster size are important monitors of the SCT performance in the 2 T magnetic field. The Lorentz angle of the SCT barrel has been measured to be θ=3.93±0.03(stat.)±0.10(syst.) degrees which is in agreement with the model prediction of θ=3.69±0.26(syst.) degrees.
