Yangyang Underground Laboratory Sun Kee Kim Seoul National University

Questions on Universe  What is the Universe made of?  How large is the Universe?  How did the Universe start?  What is the destiny of the Universe?  What is the meaning of life in the Universe?  … “The most incomprehensible thing about the world is that it is comprehensible” - A. Einstein - Some of these questions can be answered by understanding the nature of Dark matter and Neutrinos

Issues  Dark Matter What is it ? WIMP?, Axion,… What is its nature? Mass, SUSY,…  Neutrinos What is mass? Majorana or Dirac? Magentic moment? Mixing angle? “The most incomprehensible thing about the world is that it is comprehensible” - A. Einstein - Underground experiments on -Direct dark matter search -Neutrinoless double beta decay search -Neutrino magnetic moment with strong source

On going at KIMS  Dark Matter CsI(Tl) crystal detector ULE HPGe detector for low mass Cryogenic detector development  Neutrinoless double beta decay Metal(Sn,Zn,…) loaded liquid scintillator CaMoO 4 crystal detector Other crystals(PbMoO 4,CdWO 4,...) PLB 633, 201, 2006

DMRC  Dark Matter Research Center at SNU was established in funded by Creative Research Initiative program of MOST(funded up to 2009)  KIMS group for CsI(Tl) WIMP search - SNU, Kyungpook National Univ., Sejong Univ. Younsei University, Ewha Woman ’ s Univ., KRISS  International Collaboration - China: Tsinghua Univ., IHEP - Taiwan: Academia Sinica (ULE HPGe) - Japan: KEK, Saga Univ. - Russia: ITEP (DBD) - Ukrine: INR (DBD)

History  Mini-workshop on WIMP search with crystals, Seoul (Henry Wong, Jin Li)  Beijing Mini-workshop, Beijing  Cold Dark Matter Mini-workshop, Taipei  TEXONO-KIMS joint meeting, Beijing  Vasily Kornoukhov visited KIMS  TEXONO-KIMS Joint workshop, Yongpyung  KIMS visited Moscow  ITEP group visited KIMS  Chinese Funding agency visited KIMS  Fedor Danevich visited KIMS  Takayuki Matsui visited KIMS  Workshop on the underground experiments at Yangyang  Good news in 2005 Tsinghua Univ. group got funding support ITEP group got ISTC project funded
