The alignment of the CMS silicon tracker reached a remarkable precision and it is only based on track-based algorithms. This talk will present the strategies used, methods to validate the results and the results itself. An emphasis will be put on lessons learned and their application to future silicon trackers.

For the high-luminosity LHC (HL-LHC), CMS will install a new silicon tracker. As a result of the expected increase in instantaneous luminosity by a factor of five compared to the LHC design value, the granularity will be significantly increased in order to cope with the higher track density. Moreover, the expected radiation dose requires the use of more radiation hard sensor material that has...

The DEPFET vertex detector at Belle-II incorporates a structural (vibrations and
displacement) and environmental (temperature and humidity) monitor based on Fiber Bragg Gratting (FBG) optical sensors. The basic layout and principles of the monitoring system will be reviewed including results from the 2014 PXD-SVD combined testbeam and a detailed description of the FBG packaging, radiation...

The LHCb Vertex Detector (VELO) will be upgraded in 2018 to a lightweight, pixel detector capable of 40 MHz readout and operation in very close proximity to the LHC beams. The thermal management of the system will be provided by evaporative CO2 circulating in microchannels embedded within thin silicon plates. This solution has been selected due to the excellent thermal efficiency, the absence...

In order to transfer CO2 coolant from the cooling systems to the detector, coaxial vacuum insulated transfer lines have been chosen by both ATLAS IBL and CMS Pixel Phase I Upgrade. This work summarize the recent installation experience in both experiments, the issues encountered and gives some preliminary results on the performances.

The strict requirements in terms of material budget for the CLIC vertex detector (0.2% X0 per detection layer, including cables and supports) require the use of a dry gas for the cooling of the respective sensors. This, in conjunction with the compactness of the inner volumes, poses several challenges for the design of a cooling system that is able to fulfill the required detector...

The Compressed Baryonic Matter experiment (CBM) at the future FAIR facility at Darmstadt (Germany) explores the phase diagram of strongly interacting matter in the regime of highest net baryon densities with numerous probes, among them open charm. Open charm reconstruction requires a vacuum compatible Micro-Vertex Detector (MVD) with unprecedented properties, arranged in (up to) four planar...

PANDA is a key experiment of the future FAIR facility, under construction in Darmstadt, Germany. It will study the collisions between an antiproton beam and a fixed proton or nuclear target. The Micro Vertex Detector (MVD) is the innermost detector of the apparatus and its main task is the identification of primary and secondary vertices. The central requirements include high spatial and time...

A novel detector design with tilted silicon strip/pixel detector modules is being considered for the Inner Barrel section of the CMS Tracker Phase 2 Upgrade. By tilting the modules towards the interaction point the angular coverage of the modules is increased, leading to less modules needed. The layout and a support structure concept for such tilted geometry are presented.

A vertex detector with a barrel and an end-cap section, both composed of three double layers, is under development for CLIC. The strict requirements in terms of material budget (2 x 0.2% X0 per double layer, including 2 x 0.1% X0 of silicon for the...

The HFT PXL detector is a new two layer, inner, vertex detector which has just been installed in the STAR experiment at RHIC. This is the first time that a vertex detector based on MAPS[1] technology has been used in a collider experiment. The MAPS silicon chips have 20.7 micron square pixels and are thinned to 50 microns to reduce multiple coulomb scattering. The detector is configured in...

The Luminosity Detector for the PANDA experiment at FAIR/Darmstadt is a tracking device 11m downstream of the interaction point. Since we are measuring elastic pbar-p scattering as a reference channel to determine the luminosity, we need to reconstruct tracks near the non interacting antiproton beam which is stored in the HESR (high energy storage ring). We would like to share our experience...

The DEPFET Collaboration develops highly granular, ultra-thin active pixel detectors for high-performance vertex reconstruction at future collider experiments. A fully engineered vertex detector design, including all the necessary supports and services and a novel ladder design with excellent thermo-mechanical properties, is being developed for the Belle II experiment. The self-supporting...

Belle II will be the only experiment at the SuperKEKB collider in Tsukuba, Japan. Its innermost part surrounding the beam pipe - the "Vertex Detector" (VXD) - is composed of a 2-layer "Pixel Detector" (PXD) and a 4-layer "Silicon Vertex Detector" (SVD) made from double-sided silicon strip detectors. Because of the relatively low collision energy (10.58 GeV), multiple scattering and thus...

The silicon tracker of the ATLAS experiment will be replaced in 10 years’ time in readiness for the high luminosity operation of the LHC. The replacement tracker will cover 200m2 and will consist of 10,000 detector modules mounted onto a mechanical support structure. Central to the design of the support structure is the concept of a highly integrated local support (or stave) onto which 26...

The quest for low mass tracking systems for the next generation of experiments at the LHC requires extensive use of low density polymeric materials. Such materials take the form of plastics, resins in CFRP and adhesives. In this paper we attempt to summarise the results of experimental investigations into such materials within the context of developments for the LHC and other similar...

The requirements imposed by the Physics of the new particle and nuclear physics experiments and the upgrades of the existing ones on the detector trackers are more and more challenging. The required degree of expertise of the institutes participating in the design and construction of the trackers whittles down the range of possible activities that can be efficiently tackled both in terms of...

While HEP silicon detectors have embraced next generation materials, including carbon fibers, foams, and advanced resin systems, they have been slow to capitalize on the design freedom offered by composite fabrication techniques. In particular, limited use has been made of large moment of inertia structures for coupling sensors together in anything but simple shells. By creating high inertia,...

The Laser Alignment System (LAS) of the CMS Tracker detector monitors the position variation of its components with a rate of five minutes. A precision of 1 micrometer for the x and y translations, and 1.1 microradians rotation around z-axis was achieved. For rotations around x- and y-axis the achieved precision is 3.7 and 2.6 microradians, respectively.
During the cooling down test...

For the phase-2 upgrade of the LHC in about ten years from now, several detector components of the ATLAS experiment will be replaced. The planned ten times higher LHC design luminosity will result in severe radiation dose and high particle rates. The current inner detector of the ATLAS experiment will be replaced by an all silicon tracking detector.
The layout of the upgrade silicon tracking...
