ALICE TPC Online Tracking on GPU
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 analy...
متن کاملOnline 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 کاملTrack Reconstruction in the STAR TPC with a CA Based Approach
STAR [1] is an active collider heavy-ion experiment at RHIC/BNL (Upton, USA). The main tracking detector of the experiment is the Time Projection Chamber (TPC). Due to the collision rate increasing (up to 40 KHz for Au+Au 200 GeV/n and up to 1 MHz for pp 500 GeV) and recording rate (up to 10 KHz) the STAR experiment requires a fast track reconstruction procedure which can deal with high track d...
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 کاملCommissioning and Calibration of the ALICE TPC
ALICE (A Large Ion Collider Experiment) is the dedicated heavy ion experiment at the Large Hadron Collider at CERN. The main tracking device of ALICE is a large volume TPC. The milestones of the TPC commissioning as well as the current status of the detector calibration are presented. The obtained resolutions in transverse momentum, position as well as in specific energy loss (dE/dx) are presen...
