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.

TID effect makes threshold voltages shifted and leakage current of NMOS transistors in CMOS device increase, especially. Thus, a number of layout methods are implemented. For example, enclosed layout transistor (ELT) has radiation hardness against TID effects while it has large implementation area, complicated effective W/L ratio, and asymmetric source and drain capacitance. It makes circuit design difficult. Other technique except ELT needs additional layer to exploit or careful design to eliminate short problem by silicide process. However, we presented simple and powerful radiation hardness layout method which needs only layer procedure change. It has been implemented using 0.18 m CMOS process. Traditional NMOS, proposed NMOS, and ELT will be tested by using Co-60 gamma ray source up to 30 Mrad and compared about leakage current, noise at input gate, and threshold voltage shift.

It requires a highly integrated detection system with the ability to identify ion species in a high flux mixed environment. We have proposed [1] a new strategy to meet these requirements with a single CMOS pixel chip. This sensor is based on a matrix of 50×50 µm2 pixels, read out in rolling-shutter mode, and features columns ended by 3-bit ADCs with tunable threshold. An embedded digital algorithm extracts the particle properties from the hit information to provide the radiation flux on–line. A reduced scale prototype with 32×32 pixels and 32 column ADCs has been designed and fabricated in a 0.35 µm process. The layout of the identifying and counting algorithm, downstream the pixel matrix, was developed in the same process. A full simulation of this layout for a subset of columns was used to check the algorithm output against many inputs. Test results obtained with X-rays, ß- particles and laser illumination, confirm previous simulations addressing gain and linearity. Column ADCs also show expected features. Those measurements validate the possibility to monitor proton and electron fluxes up to 107 particles•cm-2•s-1 and distinguish proton from electron for energies lower than 50 MeV.

Dear sir or Madam, I am the Business Development Manager for the Department of Physics and Astronomy with special remit of Particle Physics at the Univeristy of Sheffield, UK. I work not only with the Particle Physics community, but with my colleagues in the Sheffield Science Gateway, enabling cross-faculty and cross industry collaborations to drive forward the academic research in the department. As such, I am intending to attend the TIPP conference as this is an excellent change to network and promote the activities of the academics within the field, and I was wondering about the possibility of exhibition space during the meeting to promote our activities, both in Particle Physics and Technology Transfer. I would be most grateful if you could provide me with details of costs for such space, and details to enable me to begin making the appropriate arrangements. kindest regards Richard Dr Richard J Holmes B.Sc., M.Sc., Ph.D., MRSC, C.Chem., C.Sci., AFHEA.

A reduction of several orders of magnitude of the event rate is needed to reach values compatible with detector readout, offline storage and analysis capability. The CMS experiment has been designed with a two-level trigger system: the Level-1 Trigger (L1T), implemented on custom-designed electronics, and the High Level Trigger (HLT), a streamlined version of the CMS offline reconstruction software running on a computer farm. A software trigger system requires a trade-off between the complexity of the algorithms, the sustainable output rate, and the selection efficiency. With the computing power available during the 2012 data taking the maximum reconstruction time at HLT was about 200 ms per event, at the nominal L1T rate of 100 kHz. Track reconstruction algorithms are widely used in the HLT, for the reconstruction of the physics objects as well as in the identification of b-jets and lepton isolation. Reconstructed tracks are also used to distinguish the primary vertex, which identifies the hard interaction process, from the pileup ones. This task is particularly important in the LHC environment given the large number of interactions per bunch crossing: on average 25 in 2012, and expected to be around 40 in Run II. We will present the performance of HLT tracking algorithms, discussing its impact on CMS physics programme, as well as new developments done towards the next data taking in 2015.
