    ORAL
    We report on a proton radiation damage experiment on P-Channel CCD newly developed for an X-ray CCD camera onboard the Astro-H satellite. The device has been exposed up to 10^9 protons/cm2 at 6.7 MeV. The charge transfer inefficiency (CTI) is measured as a function of radiation dose. In comparison with the CTI actually measured in the CCD camera onboard the Suzaku satellite for 6 years,...

    Radiation effects
    ORAL
    Single-event measurements on the analog ASIC developed for astronomical CCD camera systems are reported. The experiments using several heavy ions and protons exhibited positive correlation between the particle's LET (linear energy transfer) and the probability of the SEU (single event upset). The predictive SEU rate in the low earth orbit was derived on the assumption of the CCD camera...

    ORAL
    The collection of charge carriers generated in p+-n-strip sensors close to the Si-SiO2 interface before and after 1 MGy of X-ray irradiation has been investigated using the transient current technique (TCT) with sub-nanosecond focused light pulses of 660 nm wavelength, which has an absorption length in silicon at room temperature of 3.5 μm. Depending on the applied bias voltage, bias...

    ORAL
    The Pixel Luminosity Telescopes (PLT) is a dedicated luminosity monitor for CMS based on single-crystal diamond sensors. It is designed to measure the bunch-by-bunch relative luminosity to high precision. It consists of a set of small angle telescopes each with three planes of single-crystal diamond pixel sensors. The full PLT will be installed in CMS for the first full energy operation of the...

  5. 30. Recent Results of the ATLAS Upgrade Planar Pixel Sensors R&D Project*

    Pixel technologies - Hybrid pixels
    ORAL
    To extend the physics reach of the LHC experiments, several upgrades to the accelerator complex are planned. This upgrade, the HL-LHC, eventually leads to an increase of the peak luminosity by a factor of five to ten compared to the LHC design value. To cope with the higher occupancy and radiation damage also the LHC experiments will be upgraded. The ATLAS Planar Pixel Sensor (PPS) R&D...

  6. 34. Evaluation of novel n$^{+}$-in-p pixel and strip sensors for very high radiation environment

    Radiation effects
    ORAL
    We have been developing novel n$^{+}$-in-p pixel and strip sensors that are highly radiation-tolerant, having a ``planar" electrode geometry, utilize p-type silicon wafers, and being read out from highly doped n$^{+}$ implants. Our goal of the radiation level is in the range of $10^{15}$ and up to 2 $\times$ 10$^{16}$ 1-MeV-neutron-equivalent (n$_{\rm eq}$)/cm$^{2}$ of the particle fluence,...

    Ultra light mechanics and cooling
    ORAL
    Local thermal management of detector electronics through ultra-thin micro-structured silicon cooling plates is an extremely promising technique for HEP with wide potential application in other fields. It combines a very high thermal efficiency with a very low addition of mass and space, and suppresses all problems of CTE mismatch between the heat source and he heat sink. Typical...

  8. 54. Impact of pixel size and shape on physics analysis

    Data reconstruction and algorithms - Vertexing
    ORAL
    A Monte Carlo study will be presented to quantify the impact of the z resolution of the pixel detector to a new physics search. The choice of the pixel shape and size in the r-\phi and z-directions results in different position resolutions, that in turn influence the selection power for the analysis of a certain physics channel. The presented study illustrates the effect of the pixel...
