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.

It consists of an inner pixel detector, with 66 million read-out channels, and an outer 200 m² silicon strip detector with 10 millions channels. The successful operation of this detector during the first three years of LHC running with proton-proton and heavy ion collisions will be discussed. Results will include operational challenges encountered during data taking that influenced the active fraction and read-out efficiency of the detectors. Details will be given on the performance at high occupancy with respect to local observables, such as signal to noise ratio and hit reconstruction efficiency, and on radiation effects with respect to the evolution of power consumption, sensor bias, read-out thresholds and leakage current.

Abstract submitted: <https://indico.cern.ch/userAbstracts.py?confId=192695>. Status of your abstract: <https://indico.cern.ch/abstractDisplay.py?abstractId=188&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: GOETZMANN, Christophe Submitted on: 03 February 2014 10:32 Title: Tracker alignment validation in CMS using electrons Abstract content The tracker of CMS experiment is composed at one hundred percent of silicon detectors. They are arranged in successive layers of concentric cylinders around the beam axis, in the central part of CMS detector, and in disks perpendicular to the beam axis, in the forward and backward part of the detector. The whole has the shape of a cylinder of 110 cm radius and 540 cm length. The silicon detectors are of two different types, pixel and micro-strip. The pixels, having a higher granularity, are placed closest to the collision point, while the micro-strip complete the outer parts of the tracker. The aim of the tracker is to reconstruct the trajectories of charged particles. Taking advantage of the 3.8 Tesla magnetic field delivered by CMS solenoid magnet, the tracker provides a measurement of the transverse momentum of these particle, which is directly related to the radius of curvature of their trajectory. We know that the real positions of all the silicon sensors composing the tracker are not exactly the same as the designed ones. Some imperfections appear during the construction, and some other displacement of these sensors can also be progressively induced, with the effect of the magnetic field, the temperature, the weight of the detector... The disposition of all the sensors evolves with time. The goal of alignment in CMS is then to determine what are the real positions of all these sensors, to take them into account in tracks reconstruction, and improve the resolution of all tracker measurements. The precision of alignment constitutes therefore a very central issue of the CMS experiment. The best precision for alignment is obtained using minimization algorithms (Millipede, HIP). These algorithms use the information from millions of different tracks to detect and quantify the possible misalignments. Though an alignment accuracy of a few micrometers can be reach with the help of these algorithms, there exists nevertheless some particular deformations, called “weak modes”, that can not be fully retrieved with these algorithms. In this poster, I will present a tool that I have been developing to detect momentum changing weak modes. These are misalignments consisting in global rotations of tracker modules with respect to the beam axis of CMS, by a certain Δφ angle. This angle can depend either on the transverse or longitudinal position of the modules. Such deformations would impact the curvature of reconstructed tracks. And as the transverse momentum of tracks in CMS is estimated from their radius of curvature, a systematic bias would be introduced in the measurement of this quantity. For electrons, the transverse energy measured in the electromagnetic calorimeter can be used as a reference and be compared to measurement given by tracker, in order to estimate this bias. This is not made track by track, as the calorimeter energy resolution is greater than the typical expected bias. We instead use the shift eventually observed in the mean value of the E/p distributions for different energy bins. Finally, our tool uses this information to calculate an estimation of the deformation amplitude in term of the rotational angle Δφ. A selection has been defined and optimized to select good electron tracks out of events where a Z boson decays into an electron and a positron. The selection and the method have been tested using Monte-Carlo sample reconstructed with a tracker geometry on which we have introduced momentum changing misalignments of various amplitudes. The tool has also been tested on 2012 data. A sensibility of about 1 μrad/cm can be reached by using 10 000 tracks. No momentum changing weak modes have been detected for 2012 data.

To accomplish the scientific goals a high performance kaon/pion separation up to 4 GeV/c is mandatory. Because of space limitations the main components of the particle identification system will consist of DIRC (Detection of Internally Reflected Cherenkov light) detectors residing inside a magnetic field of up to 2 Tesla. A barrel DIRC with fused silica radiator bars will surround the target at a radial distance of 48 cm and will cover a polar angle range of 22 to 140 degrees; an endcap DIRC built of a segmented fused silica disc of 210 cm diameter will be installed in the forward region to cover the polar angles from 5 to 22 degrees. There are several challenging issues with the PANDA DIRCs to be discussed in this presentation: the photon rates can reach a few MHz/cm2 and photon detection inside the magnetic field is required. The limited space available for both DIRCs enforces the use of special optics to focus the Cherenkov photons onto the readout planes, its final choice being still under investigation. For the high rate signal readout several frontend options are being studied. The different design and readout options for both DIRCs were investigated with small scale prototypes using particle beams at CERN, DESY and GSI. Important results of these test runs will be presented and compared to simulations.
