  1. 56. Measurement of radioactive contamination with charge-coupled devices (CCDs)
    Dr Alvaro Chavarria (University of Chicago)
    18/03/2015, 14:30
    Contributed
    Presentation
    I will present the techniques we have developed to measure trace contamination of uranium, thorium, lead-210 and silicon-32 in the CCDs for the DAMIC experiment. I will introduce the devices, which consist of a square array of 16 million, 15 um x 15 um pixels, and a substrate thickness of 675 um. I will discuss the identification and spectroscopy (down to 100 eV) of alpha and beta particles...

  2. 64. Progress toward Cooperative Low Background Infrastructure
    Prof. Priscilla Cushman (University of Minnesota)
    18/03/2015, 14:50
    Invited
    Presentation
    The Assay and Acquisition of Radiopure Materials (AARM) collaboration includes representatives from dark matter and neutrinoless double beta decay experiments. A series of workshops have fostered communication among collaborations with mutual interests in low background studies. Within this context, we have worked to create a model for sustainable and cost-effective low background...

  3. 55. “radiopurity.org”: A Community Assays Database
    Jodi Cooley (SMU)
    18/03/2015, 15:10
    Invited
    Presentation
    The community of researchers working on experiments that require ultra-low backgrounds has an abundance of material assay results. These results are available through publications, electronic databases and through informal communications. Through a consortium of researchers, we have addressed the long standing problem through the creation of a concise and flexible data format and a database...

  4. 20. Topics on low activity electronics of the GERDA project
    Dr Carla Maria Cattadori (INFN Milano Bicocca)
    18/03/2015, 15:30
    Invited
    Presentation
    Front End electronics is a crucial and critical item in any experiment aiming at ultra Low Background. All the Dark Matter and Double Beta Decay experiments have to face the fact that the FE devices and electronic, beside being properly electronically tailored to readout the detector, hence having the proper gain, dynamic range, and resolution, must accomplish the same demanding low activity...

  5. 89. Low Background Signal Readout Electronics for the MAJORANA DEMONSTRATOR
    Mr Ian Guinn (University of Washington)
    18/03/2015, 15:50
    Contributed
    Presentation
    The MAJORANA Collaboration will seek neutrinoless double beta decay in Ge-76 using isotopically enriched p-type point contact (PPC) high purity Germanium (HPGe) detectors. A tonne-scale array of HPGe detectors would require background levels below 1 count/ROI-tonne-year in the 4 keV region of interest (ROI) around the 2039 keV Q-value of the decay. In order to demonstrate the feasibility of...
