  1. Potential sites of Deep Sea Anti-Neutrino Detector around Taiwan DOANOW workshop March 23-25, 2007 M.A. Huang1 & H.T. Wang2 1 General Education Center, National United University, Miao-Li, Taiwan, 360 2 Institute of Physics, Academia Sinica, Taipei, Taiwan, 115

  2. Nu physics and astrophysics in Taiwan TEXONO, Academia Sinica DYB, NTU • Experimental • TEXONO: Academia Sinica • DYB: NTU, NCTU, NUU • CRTNT: NUU • Theoretical • NCTU, NCTS • NUU NCTU, NCTS CRTNT, NUU NUU M.A. Huang

  3. TEXONO Collaboration Taiwan EXperiment On NeutrinO Collaboration : Taiwan (AS, INER, KSNPS, NTU) ; China (IHEP, CIAE, THU, NJU) ; Turkey (METU) ; USA (UMD) Program: Low Energy Neutrino & Astroparticle Physics • Kuo-Sheng (KS) Reactor Neutrino Laboratory KS NPS-II : 2 cores  2.9 GW KS nLab: 28 m from core#1 NPS-IV (under construction) M.A. Huang

  4. TEXONO Physics topics • Neutrino magnetic moments, • PRL, 90, 2003; hep-ex/0605006 • Axion searches • Astro-ph/0609001, • Nu-e cross sections • Undergoing analysis • Ultra-Low-Energy HPGe Prototype • ~100 eV, 4x5g detector, working on1 kg detector. • Nu-N coherent scattering • Dark matter searches M.A. Huang

  5. CRTNT • CRTNT : Cosmic Ray Tau Neutrino Telescope • Detect shower from , which comes from Earth-skimming  Z. Cao et al., J. Phys. G,31, 571-582, (2005) Highlight paper of the year 2005 by J. Phys. G M.A. Huang

  6. Future plan of CRTNT 4 stations, each havetelescopes, cover 1664 field of view. Site: Balikun, Hsing-Jiang Energy range: E >100TeV for neutrino, and E >0.1EeV for UHECR. UHECR Mountain-passing  event Earth-skimming  event C M.A. Huang

  7. Daya Bay collaborators in Taiwan • Nat’l Taiwan Univ. • PI: Yee Bob Hsiung • Acrylic vessel • Nat’l Chiao Tung Univ. • PI: G.Y. Lin • Nat’l United Univ. • PI: C.H. Wang • Y. Chang, S. Blyth Muon veto simulation, Aberdeen Tunnel prototype

  8. Potential sites near Taiwan • Selection requirements: • Near nuclear power plant ~ 60 -100 km. • Depth < -2.6 km (~ 1 km of std. rock) • Distance to nearest harbor • Logistic support

  9. Nuclear Power Stations 3 existing NPS, all have two cores. NPS-1: 2  1775 MWt NPS-2: 2  2894 MWt NPS-3: 2  2785 MWt NPS-4 in construction. NPS-4: 2  4100 MWt ; Finish in 2009~ 2101

  10. Northern Taiwan sites NP-1,2 are too far! only -1600 m

  11. Northern Taiwan only -1600 m NP-4 is within 100 km! Site A: -3500 m

  12. Southern Taiwan Site B: -2500 m Site C: -2500 m Site D: -3000 m Site E: -4000 m

  13. Summary NPS-3: 2  2785 MWt

  14. Future participation in HANOHANO • If HANOHANO site is near Taiwan, we would be the host and provide local supports. • Site survey • Application/permission to government • Local control • Data transmission, storage, … etc. • If not, … • HANOHANO is a good continuation of DYB, someone may still participate. • Need consensus from colleague in Taiwan • HEP community, geo-physicists, funding agency, publics.
