Global Tracking Unit for ALICE TRD
نویسندگان
چکیده
The ALICE TRD Detector employs 1080 optical links for data readout. The FEE chips (TRAP [1]) form a readout tree running at 8 bit 120 MHz double data rate. The tracklet and raw data are sent over the Optical Readout Interface (ORI) at 2.5 Gbit/s. The Global Tracking Unit (GTU) serves as data receiver and fast track finder and contributes to the L1 trigger decision. Finally, after L2 accept the complete event is sent optically to the DAQ.

First High-Energy Collisions with the ALICE TRD Global Tracking Unit
The Transition Raditation Detector (TRD) of the ALICE experiment is designed to provide fast triggers based on the online reconstruction of charged particle tracks within approximately 6.5μs after the collision. A total of 1.2 million analog channels for 540 readout drift chambers are processed by more than 65 500 multi-chip modules to find and parameterize short track segments. Via 1 080 optic...

The Transition Radiation Detector (TRD) of the ALICE experiment at LHC is designed to provide electron/pion identification and tracking of all charged particles [1]. The TRD will supplement the TPC electron/pion identification by a pion rejection factor of the order of 100 at momenta above 1 GeV/c, allowing precision measurements of quarkonia. Sophisticated on-detector electronics [2] is design...

The Transition Radiation Detector (TRD) of the ALICE experiment at CERN incorporates 1.2 million channels which are individually read out and processed. The front-end electronics (FEE) utilizes two custom chips: an 18 channel analog preamplifier and shaper (PASA) and a mixed-signal chip, performing 10 bit analog-to-digital conversion, event buffering and local tracking (TRAP). Both chips togeth...
متن کاملLow mass diffractive systems at LHC
Diffractive reactions in proton-proton collisions are characterized by the presence of rapidity gaps and by forward scattered protons. A diffractive trigger can therefore be defined by the tagging of the forward proton or by the detection of rapidity gaps. I present a diffractive trigger scheme for the ALICE detector at the large hadron collider LHC and discuss some physics topics. In particula...
