Paul O'Connor (Department of Physics)05/09/2014, 09:10Over the next 5 years, the Large Synoptic Survey Telescope collaboration will construct a new 8m-class ground-based telescope and 3 Gpixel camera to perform an all-sky survey in the optical and near IR. Science themes of LSST include fundamental cosmology (testing the lambda-CDM paradigm and search for new physics), galactic astronomy (assembly history of the Milky Way), Solar System astronomy...Go to contribution page

Oliver Grimm (Eidgenoessische Tech. Hochschule Zuerich (CH))05/09/2014, 09:40The Spectrometer/Telescope Imaging X-rays (STIX) is a remote sensing instrument developed to perform X-ray imaging and spectroscopy of solar flares. The imaging is realized by a Fourier-imaging technique using tungsten grid collimators in front of CdTe pixel detectors. The detectors are used for an X-ray spectrometer unit based on the IDeF-X HD ASIC front-end to perform high resolution...Go to contribution page

Javier Tiffenberg (Fermi National Accelerator Lab. (US))05/09/2014, 10:10The DAMIC experiment uses high resistivity, fully depleted CCD's as detectors to search for dark matter particles. The low electronic readout noise (RMS ~2 electrons) of the CCD's make possible to reach a detection threshold below 50 eV of deposited energy by nuclear recoils in the silicon target. Owing to these characteristics, DAMIC has an unrivaled sensitivity to WIMPs with masses...Go to contribution page

Emily Macuk (Fermilab)05/09/2014, 11:00Dark Energy, the driving force for the accelerated expansion of the Universe, has become one of the largest mysteries in our current understanding of Nature. There are several ongoing, and planned astronomical projects to map large scale structure and geometry of the Universe to investigate this. During this talk we will present the newly developed Microwave Kinetic Inductance Detectors,...Go to contribution page

Ashley Joy (UCL)05/09/2014, 11:30A new, modular toolkit for creating simulations of 2D X-ray pixel detectors, X-CSIT (X-ray Camera SImulation Toolkit), is being developed. The toolkit uses three sequential simulations of detector processes including photon interactions, electron charge cloud spreading with a high charge density plasma model and many electronic components used in detector readout. In addition, because of the...Go to contribution page

Chorong Kim (KERI)05/09/2014, 12:00With the help of steady efforts to overcome the size limitations of CMOS image sensors, the development of high resolution flat-panel x-ray detectors based on CMOS technology have been greatly valued. Especially, CMOS active pixel sensors (APSs)-based detectors, which have low-noise, high-speed characteristics, are considered to be appropriate for mammography and fluoroscopy applications. This...Go to contribution page

Yashika Bansal (U)POSTERThe aim of this project is to bring advanced silicon pixel detector technology to the world of neutron scattering. Such devices would revolutionize the resolution capabilities of detectors by an order of magnitude for detectors up to 1 sq m active area when tiled up. The Project is supported by the Subatomic Group at the University of Bergen (UiB) and SINTEF at Oslo, Norway where facilities...Go to contribution page
