  4. TEXONO Overview Program: • Kuo-Sheng Reactor Neutrino Laboratory ※ reactor : high flux of low energy electron anti-neutrinos ※mn0  anomalous n properties & interactions • ※ n physics full of surprises , need intense n-source • study/constraint new regime wherever experimentally accessible • explore possible new detection channels • R&D Projects Poineering Efforts : “Zero-Background Experiment” ! • KS Expt:1st large-scale particle physics experiment in Taiwan • TEXONO Coll. : 1st big research Coll. % Taiwan & China [feature report in Science, Vol. 300, 1074 (2003) ]

  6. Kuo-Sheng Nuclear Power Plant KS NPS-II : 2 cores  2.9 GW KS nLab: 28 m from core#1

  7. Kuo Sheng Reactor Neutrino Laboratory Front Gate Front View (cosmic vetos, shieldings, control room …..) Configuration: Modest yet Unique Flexible Design: Allows different detectors conf. for different physics Inner Target Volume

  8. KS Expt: Period I Detectors ULB-HPGe [1 kg] CsI(Tl) [46 kg] FADC Readout [16 ch., 20 MHz, 8 bit] Multi-Disks Array [600 Gb]

  9. Kuo Sheng Reactor Neutrino Laboratory : First Results

  10. Reactor mn(ne) Sensitivities Gn Sensitivities

  11. Coverage in International Press

  12. Reactor Neutrino Interaction Cross-Sections P2: SM(ne) > 2 MeV P1: MM (ne) 1-100 keV P3+: Coh. (nN) < 1 keV

  13. R&D Projects • Explore New Detectors Scenarios (LEn, CDM …) • other crystal scintillators • ultra low energy HPGe [ O(100 eV) threshold ] • CsI(Tl) for Dark Matter Searches CsI(Tl) CDM search @ Korea by KIMS Coll. • Upgrading FADCs (+ FPGA etc. capabilities…..) for LEPS@SPring8 • Trace Radio-purity with AMS( Accelerator Mass Spectrometry)  1st goal : sensitivity of 10-14 g/g in 40K • Sono-LuminescenceProject (inter-disciplinary)

  14. Kuo-Sheng + Wan-Li Site • Geographically possible for medium baseline experiment for “q13” • Merits / Our Offer : • Easy reach from city • Access to Plant established • Road tunnel at 2 km • 100 m rock overburden Contacts with International Team

  15. TEXONO’s standpoint/position :: Date: Wed, 21 May 2003 16:36:25 +0800 (CST)  From:Henry Tsz-king Wong <htwong@phys.sinica.edu.tw>To: ……………………….Subject: Re: Future Reactor Experiments ……..  We are aware of this possibility and havediscussed a bit among ourselves. Our thinking isthat we will not just  "go out and do the experimentourselves." (we are busy with ongoing things, andthe required resources will be beyond what we can have on our own). However, if therewould be an internationalteam who would bring in a strong scientific case andsubstantial resources, we would be interested to explore the scenario of performing such an experimentin Taiwan. A 1% measurement of the reactor spectra isvery tricky, and I agree that having too many coresmay not be a positive aspect.…………….

  16. Possibility and Offer Raised to International Study Group: …. a 140 page document !!!

  17.  "B2" is the space at sub-basement 80 m from one of the cores. It can be considered "generically" what one can expect -- i.e. there are other buildings in the plant that may have similar space at the same level. Distances from the two cores would be different of course.

  18. Site(28 m) is the  "mirror" site to our present lab at the other core Site(23 m) is some storage space we have now. It is at the 4F of the reactor building.

  19. site-views give a general impression of the plant. You can see it is spacious to bring in containers .... etc. Also see the slopes -- and the  "no digging“ sign.

  20. Wanli (萬里) Tunnel is the road tunnel 2 km from the plant. We make close and far views. There are three auxillary tunnels (one shown).

  21. Summary & Outlook • Taiwan Experimental Particle Physics asmall & young but vibrant community • TEXONO Collaboration  Built-Up and Growing • Kuo-Sheng Neutrino Lab.: Established & Operational Physics Data Taking since June 01 Results published on mn (Gn) More topics under way • Diversified R&D Program in parallel • Reactor q13 experiment : Kuo-Sheng Plant+Wan-Li Tunnel submitted for consideration  Our hands are tight, but we keep our mind, eyes & heart open

  22. Some Personal Thoughts : (forgive me if I am incorrect) • Hidden/higher agenda of this meeting besides/beyond neutrinos ?? • VALUE of the project not only on the scientific contents BUT also the infrastructures/traditions it can build up
