Testbeam-2004 Analysis


This group includes: Neil Knecht, Peter Krieger, Lianliang Ma and Pekka K. Sinervo. the data sample and the Monte Carlo (MC) simulation, more information about our work can be found with the reports listed below.

The top view of the setup for testbeam 2004 is shown in the below plot. The calorimeter is located in the open circle, and consists of: ElectroMagnetic calorimeter at EndCap (EMEC), Forward Calorimeter (FCal) and Hadronic Calorimeter at EndCap (HEC). The front-view and side-view of the H6 setup are also shown as below. The data was collected during two run phases: RunI and RunII, with beam particle electron, pion and muon. In the Frontveiw plot, the vertical green line means where y-scan data is collected, the horizontal green line for x-scan, and A-H points for e(nergy)-scan. More information about the testbeam data can be found here. You can also visit the web for the information collected by Neil (Click here).

With this testbeam data, we can study:
(1) Study transition region at pseudorapidity 3.2;
(2) Intercalibrate subdetectors;
(3) Study dead material energy losses;
(4) Study tails in energy resolution;
(5) Validate Geant4 (toolkit for detector simulation);
(6) Study hadronic energy weighting schemes
and so on.

Now we are focusing on the beam-tracking algorithm, and S-shape of EMEC, more detailed information can be available in the reports presented recently:
