Tracking is essential for the reconstruction of objects like jets, muons, electrons and tau leptons starting from the raw data from the silicon pixel and strip detectors. Track reconstruction is widely used also at trigger level as it improves objects tagging and resolution. The CMS tracking code is organized in several levels, known as 'iterative steps', each optimized to reconstruct a class of particle trajectories, as the ones of particles originating from the primary vertex or displaced tracks from particles resulting from secondary vertices. Each iterative step consists of seeding, pattern recognition and fitting by a kalman filter, and a final filtering and cleaning. Each subsequent step works on hits not yet associated to a reconstructed particle trajectory. The CMS tracking code is continuously evolving to make the reconstruction computing load compatible with the increasing instantaneous luminosity of LHC, resulting in a large number of primary vertices and tracks per bunch crossing. This is achieved by optimizing the iterative steps and by using new software techniques. Tracking algorithms used in CMS are described; physics and computing performances are discussed with respect to Run 1 and Run 2 physics program and within CMS future upgrades.

Abstract content The Large Hadron Collider forward (LHCf) experiment is designed to measure the hadronic production cross sections of neutral particles emitted in the very forward angles in p-p collision at the LHC. LHCf has reported energy spectra of forward photons and neutral pions at √s = 900 GeV and 7 TeV proton-proton collisions measured at LHC. Forward spectra can be helpful in verifying cosmic ray interaction models. The next operation in 2015 is expected under much higher radiation dose. Therefore, we are upgrading the detectors, especially their scintillators, to be radiation harder one. Plastic scintillator layers and Scintillating Fiber (SciFi) tracker are replaced with GSO layers and fine GSO hodoscope respectively. Basic properties of new sensors of the upgraded detector are measured by 400 MeV/n carbon beams at the Heavy Ion Medical Accelerator in Chiba (HIMAC) in June, 2012. Energy resolution and position resolution of the upgraded detector are evaluated by using electron beams of 50-250 GeV at Super Proton Synchrotron (SPS) in summer, 2012. The results are understood by Monte Carlo simulations and are good enough for the requirements of the LHCf experiment.

Abstract submitted: <https://indico.cern.ch/userAbstracts.py?confId=192695>. Status of your abstract: <https://indico.cern.ch/abstractDisplay.py?abstractId=193&confId=192695>. See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: Mr. ZABI, Alexandre Submitted on: 04 February 2014 20:32 Title: The CMS calorimeter trigger upgrade for the LHC Run II Abstract content The CMS experiment implements a sophisticated two-level online selection system that achieves a rejection factor of nearly 10e5. The first level (L1) is based on coarse information coming from the calorimeters and the muon detectors while the High-Level Trigger combines fine-grain information from all sub-detectors. During Run II, the LHC will increase its centre of mass energy up to 13 TeV and progressively reach an instantaneous luminosity of 2e34 cm-2s-1. In order to guarantee a successful and ambitious physics program under this intense environment, the CMS Trigger and Data acquisition system must be consolidated. In particular the L1 calorimeter Trigger hardware and architecture will be modified. The goal is to maintain the current thresholds (e.g., for electrons and photons) and improve the performance for the selection of tau leptons. This can only be achieved by designing an updated trigger architecture based on the recent microTCA technology. Racks can be equipped with fast optical links and latest generation FPGAs can be used. Sophisticated object reconstruction algorithms as well as online pile-up corrections can thus be envisaged. The plan to consolidate the CMS trigger system will be presented as well as the recent hardware and firmware developments. Algorithms to select efficiently electrons, photons, tau leptons or jets will also be presented along with the expected performance. Summary The presentation will cover details of the CMS data acquisition and trigger upgrade planned for the next run at the LHC, concentrating on the replacement of the Level-1 calorimeter trigger. As the LHC restarts and delivers higher luminosity collisions, exceeding the design parameters, the current CMS trigger system will not be capable of maintaining the high efficiency required for the CMS physics programme. The replacement of the trigger system is also a good opportunity to consider even more efficient ways of selecting electrons, photons, tau leptons, reconstructing jets and performing energy sums. In these intense conditions, the implementation of pile-up mitigation techniques is required to reach acceptable performance. Modern technologies offer an effective solution to achieve these goals. The trigger primitives generated by the detector will be transmitted by newly installed optical link boards (4.5 to 6.4 Gb/s) replacing the existing copper cables (1.2 Gb/s), to a new system based on the microTCA electronics standard. The system is based on custom designed AMC (Advanced Mezzanine Boards) with Xilinx Virtex 7 FPGAs. These FPGAs use 10Gb/s MGTs to gather information from the entire calorimeter for each event in one FPGA, where sophisticated algorithms may be implemented. The complete view of the calorimeter will allow the trigger to compute global quantities such as the average energy density that can be used to estimate the pile-up level. The resulting increase in rejection power will permit the experiment keep low trigger thresholds on physics objects. The talk will cover the design, development and testing of the components of the new trigger system, including results from recent demonstrator systems at CERN and elsewhere. The talk will also detail the algorithms under study, and put in perspective the CMS physics goals for the next LHC run. The new system will allow the experiment to efficiently select low momentum leptons to pursue the full characterisation of the Higgs sector, in particular including VBF production modes, as well as searching for cascades initiated by SUSY particles.

The TileCal is regularly monitored and calibrated by several different calibration systems: a Cs radioactive source that illuminates the scintillating tiles directly, a laser light system to directly test the PMT response, and a charge injection system (CIS) for the front-end electronics. These calibrations systems, in conjunction with data collected during proton-proton collisions, provide extensive monitoring of the instrument and a means for equalizing the calorimeter response at each stage of the signal propagation. Through the individual calibrations provided by these systems, we are able to achieve a precision of approximately 0.5-1.0% in the monitoring of the evolution of the response of the different components of TileCal. Analysis of the combined calibrations is used to observe the gain variance in the detector response. This contribution presents a brief description of the different TileCal calibration systems with the latest results on their performance during the LHC Run I.

Together with other calorimeters, it provides precise measurements of hadrons, jets, taus and missing transverse energy. The monitoring and equalisation of the calorimeter response at each stage of the signal development is allowed by a movable 137Cs radioactive source, a laser calibration system and a charge injection system. Moreover, during the LHC data taking, an integrator based readout provides the signals coming from inelastic proton-proton collisions at low momentum transfer (minimum bias currents) and allows to monitor the instantaneous ATLAS luminosity as well as the response of calorimeter cells. Minimum bias currents have been used to detect and quantify the effect of TileCal scintillators irradiation using the data taken during 2012 that corresponds to about 21 fb-1 of integrated luminosity. Moreover, the response variation for an irradiated cell has been studied combining the information from three calibration systems (cesium, laser and minimum bias). The result of the irradiation on the calorimeter response will be reported.
