DM-Ice-17 From Seon-Hee IceCube lab Successfully deployed on Dec. 2010! Detectors: 50m 2004: Project start • Two 8.5 kg NaI detectors 2010/2011: 7 Strings from NAIAD (17 kg total) installed, Project completed with 86 strings Goals: IceCube In-Ice array 80 strings each with 60 DOMs • Assess the feasibility of AMANDA-II array deploying NaI(Tl) crystals in (IceCube pre-cursor) 1450m the Antarctic Ice for a dark DeepCore matter detector 6 strings each with 60 high quantum efficiency DOMs; optimized for low • Establish the radiopurity of energies the antarctic ice / hole ice 2450m • Explore the capability of 2820m IceCube to veto muons Currently taking data bedrock continuously since Jan. 2011 Monday, October 3, 2011
DM-Ice-17 Construction & Deployment Transport across the Ice Detector assembly Flying to Antarctica Detector in the hole DM-Ice and IceCube Deployment DOMs awaiting Team 2 installation Monday, October 3, 2011
DM-Ice Sensitivity Sensitivity (90% CL) with null hypothesis: 250-kg / 2-year running time J. Cherwinka et al., arXiv: 1106.115 6 • Lower the E threshold the better the sensitivity. • Higher the E threshold , more BG control is needed. Monday, October 3, 2011
DM-Ice Full Detector Concept • Segmented 20” diameter x 10” long NaI detector (~200 kg) • Stainless steel pressure vessel • Copper shielding if needed • Electronics & pulse digitization in the vessel • location: ~150 cm • ~ 2500 m deep in the ice, • near the center of IceCube for additional veto • Local muon veto We might need total 2 -3 modules like this. Final design might change. ~65 cm Monday, October 3, 2011
