Dr Héctor Gómez-Maluenda (University of Zaragoza)27/07/2010 15:50Dark Matter Direct SearchesTalkGermanium detectors have been used in several experiments searching for Rare Events due to their good features (detection efficiency, energy resolution or robustness). New generation detectors, like broad energy detectors or segmented ones, could improve the sensitivity of this kind of experiments since different background rejection techniques could be developed without losing detection...Go to contribution page

Prof. Daniel McKinsey (Yale University)27/07/2010 16:10TalkKnowledge of the energy scales for nuclear recoil-induced signals is crucial for determining the sensitivity of any WIMP detector. I will present a number of experiments recently performed at Yale University to measure the nuclear recoil scintillation and ionization yields in liquid xenon, as well as the nuclear recoil scintillation yields in liquid argon and liquid neon. I will also describe...Go to contribution page

Daniel McKinsey (Yale University)27/07/2010 16:30Dark Matter Direct SearchesTalkThis talk reviews the MiniCLEAN dark matter detector's technology and status, where CLEAN stands for Cryogenic Low Energy Astrophysics with Noble gases. MiniCLEAN uses single phase argon or neon as detection medium and relies on pulse-shape discrimination to remove electronic recoil backgrounds. The anticipated sensitivity of the 150 kg of argon in its fiducial volume to the...Go to contribution page

Dr Marco Selvi (INFN - Bologna)27/07/2010 16:50TalkPresented by M. Selvi on behalf of the XENON1T collaboration. Within the XENON program, we are operating a double-phase TPCs using liquid xenon (LXe) as target material. The current phase, XENON100 installed in the LNGS, is in science mode since the beginning of 2010, with a sensitivity goal of 2 x 10-45 cm2. For the next step, we propose to build a detector with a total mass of 2.4 tons...Go to contribution page

Dr Ysrael Richard Ortigoza Paredes (University of Zaragoza)27/07/2010 17:10TalkThe ROSEBUD (Rare Objects SEarch with Bolometers UndergrounD) Collaboration has tested scintillating bolometers of BGO, Al2O3 and LiF in a common experimental set-up in an ultralow background environment at the Canfranc Underground Laboratory. We present the new results of a recent analysis of the data obtained. The BGO heat and light response to different particles has been measured, focusing...Go to contribution page

Dr Francisco Jose Iguaz Gutierrez (IRFU/CEA-Saclay)27/07/2010 17:50TalkThe status of the solar axion search with the CERN Axion Solar Telescope (CAST) will be discussed. Results from the first part of CAST phase II where the magnet bores were filled with 4He gas at variable pressure in order to scan ma up to 0.4 eV will be presented. From the absence of excess X-rays when the magnet was pointing to the Sun, we set a typical upper limit on the axion-photon...Go to contribution page

Shigetaka Moriyama (ICRR, University of Tokyo)27/07/2010 18:10Dark Matter Direct SearchesTalkThe XMASS project aims to study low-energy solar neutrinos, dark matter and double beta decay using ultra pure liquid xenon. As a first step of the project, a detector with 800kg of liquid xenon in a signle phase was proposed. The detector is now finishing its construction in the Kamioka mine in Japan. Construction of the detector will be reported and commissioning plan will be discussed.Go to contribution page
