ALICE TPC Online Tracking on GPU
نویسندگان
چکیده
For the ALICE High Level Trigger a fast tracking algorithm was developed by Sergey Gorbunov based on the Cellular Automaton method and the Kalman filter [1], that is currently installed in the HLT. For an efficient handling of upcoming lead-lead collisions in 2010 with a tremendous increase of clusters and tracks, possibilities for a better usage of parallelism and many core hardware were analyzed. The tracker itself was designed with parallel approaches in mind. A SIMD approach was realized by Matthias Kretz [2] in his diploma thesis and further the tracker was adopted to run on the NVIDIA CUDA framework [3].

Online monitoring for the ALICE-TPC commissioning∗
ALICE [1] is A Large Ion Collider Experiment which will start operation in 2007 in the course of the CERN LHC program. The main tracking device of the experiment is a cylindrical Time Projection Chamber [2] (TPC). A ROOT based software module was developed to monitor online the data stream from the TPC during the commissioning phase at CERN in 2006. The main features of the program as well as r...

متن کاملOn-line reconstruction algorithms for the CBM and ALICE experiments
This thesis presents various algorithms which have been developed for on-line event reconstruction in the CBM experiment at GSI, Darmstadt and the ALICE experiment at CERN, Geneve. Despite the fact that the experiments are different — CBM is a fixed target experiment with forward geometry, while ALICE has a typical collider geometry — they share common aspects when reconstruction is concerned. ...
متن کاملOnline Drift Velocity Calibration with the Laser System of the ALICE-TPC
The online drift velocity calibration method provides calibration parameters required at the very beginning of the offline reconstruction process in order to determine the z position of the particle tracks with a sufficient accuracy before the combined track finding [2]. It uses the TPC Laser System which generates 336 straight laser tracks, similar to ionizing particle tracks, at known positio...
متن کاملHigh Level Trigger Using ALICE ITS Detector
The high PT trigger capabilities of the ALICE inner tracking system (ITS) as a standalone detector have been investigated. Since the high PT charged particles mostly lead to the linear trajectories within this ITS sector, it is possible to select tracks of PT of the order of 2 GeV and above by confining to a narrow search window in the (θ, φ) space. Also shown that by performing a principal com...
