Dr Alessandro Gabrielli (Universita e INFN (IT))5/3/12, 8:00 PMWe describe the design of a floating gate-based MOS sensor embedded in a read-out CMOS sensing element used as a radiation sensor. The read-out cell asynchronously triggers an all-digital Ultra-Wide Band (UWB) transmitter operating in a 0-5GHz band, with a repetition frequency, which dynamically depends on the radiation level. The trigger signal ranges 20 to 30MHz, with a designed sensor input...Go to contribution page

Jason Gilmore (Texas A & M University (US))5/3/12, 8:00 PMAddressing challenges of triggering in the High Luminosity LHC environment require development of fast and efficient track-based triggering methods. We consider a dedicated electronics-based system, which could be used as a co-processor performing fast tracking using data from the pixel detector for events passing the CMS Level-1 trigger. In this scenario, a list of tracks above a certain...Go to contribution page

Dr Filippo Maria Giorgi (Universita e INFN (IT))5/3/12, 8:00 PMA digital architecture for fast sparsified readout has been developed for the implementation of wide 3D pixel sensors. The Italian VIPIX collaboration is realizing two prototypes exploiting the Tezzaron-Chartered vertical integration process in order to build a 12k-pixel 3D deep n-well MAPS sensor, and a 3D 4k-pixel front-end chip, with 50 um pitch, for a fully depleted silicon sensor. In both...Go to contribution page

Matteo Mario Beretta (Istituto Nazionale Fisica Nucleare (IT))5/3/12, 8:00 PMWe present a fast general-purpose algorithm for high-throughput clustering of data ”with a two dimensional organization”. The algorithm is designed to be implemented with FPGAs or custom electronics. The key feature is a processing time that scales linearly with the amount of data to be processed. This means that clustering can be performed in pipeline with the readout, without suffering...Go to contribution page

Mr Christian Irmler (HEPHY Vienna)5/3/12, 8:00 PMB-factories like the KEK-B in Tsukuba, Japan, operate at relatively low energies and thus require detectors with very low material budget inside the sensitive volume in order to minimize multiple scattering. On the other hand, front-end chips with short shaping time like the APV25 have to be placed as close to the sensor strips as possible to avoid excessive noise, which is mainly caused by...Go to contribution page

Dirk Wiedner (Ruprecht-Karls-Universitaet Heidelberg (DE))5/3/12, 8:00 PMThe proposed mu3e experiment will study the lepton flavor violating decay mu->eee which is strongly (10^-50) suppressed in the standard model, but enhanced to observable levels in many models for new physics. In order to achieve the proposed branching ratio sensitivity of 10^-16 the detector has to have high rate capability and good background suppression, which in turn requires excellent...Go to contribution page

Jerome Baudot (Institut Pluridisciplinaire Hubert Curien (FR))5/3/12, 8:00 PMWe propose to enhance the performances of tracking layers by building a sandwich of low power time-integrating CMOS pixel sensors. Sensors equipping one side of the layer offer a high spatial resolution (few μm), while the sensors on the other side focus on the time resolution (few μs). The whole device targets a material budget lower than 0.5 % of X0. We will present the in-beam test results...Go to contribution page

Prof. Mani Tripathi (UC Davis)5/3/12, 8:00 PMThe 3-D track trigger concept being developed for the CMS upgrade involves interconnections for signals to be transmitted between various layers of sensors and readout electronics. In this design, the two sensitive layers are separated by an interposer, which provides the lever arm for measuring transverse momenta. Such an assembly would require new challenges for bump-bonding of large...Go to contribution page

Filippo Bosi (INFN Pisa)5/3/12, 8:00 PMIn HEP experiments the use of pixel detectors requires that high power density in the sensitive area (up to 2 W/cm2) should be carried away by efficient thermal systems, eventually integrated in the light mechanical support structures. The micro-channel cooling technology is featured by a highly efficient thermal exchange and it can profit by the miniaturization technique applied on...Go to contribution page

Bob Stanek (Argonne National Laboratory (US)), David Underwood (Argonne National Laboratory (US)), Dr Waruna Fernando (Argonne National Laboratory)5/3/12, 8:00 PMOptical links will be an integral part of intelligent tracking systems at various scales from coupled sensors through intra-module and off detector communication. These links will be particularly useful if they utilize light modulators which are very small, low power , high bandwidth, and are very rad-hard. Because of concern with the reliability, bandwidth, power, and mass of...Go to contribution page

Farah Khalid (F)5/3/12, 8:00 PMMonolithic Active Matrix with Binary Counters (MAMBO) IV ASIC has been designed for detecting and measuring low energy X-rays from 6-12keV. A nested well structure with a buried n-well (BNW) and a deeper buried p-well (BPW) is used to electrically isolate the detector from the electronics. BNW acts as an AC ground to electrical signals and behaves as a shield. BPW creates a homogenous electric...Go to contribution page

Dr Markus Friedl (Austrian Academy of Sciences (AT))5/3/12, 8:00 PMIn an environment with high occupancy and continuous collisions, conventional readout of silicon strip detectors will lead to ambiguities in the time domain. This problem can in principle be minimized by reducing the shaping time, but that approach is limited by the noise penalty. The APV25 chip, originally developed for the CMS experiment, includes an on-chip switched capacitor filter...Go to contribution page

Prof. Mauro Villa (Universita di Bologna e INFN (IT))5/3/12, 8:00 PMThe capability to perform extremely fast track reconstruction online is becoming more and more important for the LHC upgrade as well as the next generation of HEP experiments, where the expected instantaneous luminosities (in excess of 10^34 /cm^2/s) and the very low signal/background ratio ask for fast and clean identification of the main characteristics of interesting events. The Slim5 R&D...Go to contribution page

Mauricio Garcia-Sciveres (Lawrence Berkeley National Lab. (US))5/3/12, 8:00 PMWe present updated results of prototyping silicon and carbon foam composite wafers for use as either low mass interposers or active hybrids. Composite 4 inch wafers have been prototyped with approximately 4 mm thickness and average density 20% that of silicon. A composite wafer consists of top and bottom silicon face-plates on a carbon foam core, assembled with adhesive that can withstand 300...Go to contribution page

Dr Stefano Zucca (University of Pavia and INFN)5/3/12, 8:00 PMIn the last decade, the use of standard deep submicron CMOS technologies for the implementation of monolithic active pixel sensors for HEP experiments has been thoroughly investigated. One of the main issues with this approach is the fact that the charge collection efficiency may be negatively affected by the presence of competitive N-wells used to integrate PMOS transistors in the readout...Go to contribution page

Daniel Magalotti (Universita e INFN (IT))5/3/12, 8:00 PMModern experiments search for extremely rare processes hidden in much larger background levels. As the experiment complexity and the accelerator backgrounds and luminosity increase we need increasingly complex and exclusive selections. We present the first prototype of a new Processing Unit, the core of the FastTracker processor for Atlas, whose computing power is such that a couple of...Go to contribution page

Dr Carlos Marinas Pardo (Bonn University)5/3/12, 8:00 PMThe new e$^{+}$e$^{-}$ colliders impose unprecedented demands to the performance of the vertex detectors. To achieve the required resolution in the vertex reconstruction, besides highly segmented pixel detectors, the material budget has to be kept at very low levels to reduce the multiple Coulomb scattering. These requirements are even more challenging in the case of the new Japanese Super...Go to contribution page
