The ALICE Inner Tracking System Upgrade
A central component of the ALICE Upgrade will be a completely new Inner Tracking System (ITS). The performance of the new ITS will be a significant improvement over that of the present ITS, in particular in the areas of material budget, granularity, a reduced radial distance from the first layer to the beam and rate capability. This will enable many key measurements of the properties of the qua...
متن کاملUpgrade of the Inner Tracking System of ALICE
The upgrade of the Inner Tracking System (ITS) of ALICE is planned for the second long shutdown of the LHC in 2019–2020. The ALICE physics program after the shutdown requires the ITS to have improved tracking capabilities and improved impact parameter resolution at very low transverse momentum, as well as a substantial increase in the readout rate. To fulfill these requirements the current ITS ...
متن کاملAlignment of the ALICE Inner Tracking System with cosmic-ray tracks
ALICE (A Large Ion Collider Experiment) is the LHC (Large Hadron Collider) experiment devoted to investigating the strongly interacting matter created in nucleus-nucleus collisions at the LHC energies. The ALICE ITS, Inner Tracking System, consists of six cylindrical layers of silicon detectors with three different technologies; in the outward direction: two layers of pixel detectors, two layer...
متن کاملRevision of the ALICE TRD tracking code
A. Bercuci1,3, M. Fasel2, and M. Ivanov1 1GSI, Darmstadt, Germany; 2Technische Universitaet, Darmstadt, Germany; 3On leave from NIPNE, Bucharest, Romania The algorithm for tracking is the backbone of the reconstruction procedure of the TRD detector of the ALICE experiment at LHC at CERN. Its performance has immediate influence on other reconstruction tasks such as calibration, alignment and par...
متن کاملThe ALICE analysis train system
In the ALICE experiment hundreds of users are analyzing big datasets on a Grid system. High throughput and short turnaround times are achieved by a centralized system called the LEGO trains. This system combines analysis from different users in so-called analysis trains which are then executed within the same Grid jobs thereby reducing the number of times the data needs to be read from the stor...
