TEXONO Overview Poineering Efforts : “Zero-Background Experiment” ! KS Expt: 1 st large-scale particle physics experiment in Taiwan TEXONO Coll. : 1 st big research Coll. % Taiwan & China [feature report in Science, Vol. 300, 1074 (2003) ] Program: Kuo-Sheng Reactor Neutrino Laboratory ※ reactor : high flux of low energy electron anti-neutrinos ※ m 0 anomalous properties & interactions ※ physics full of surprises, need intense -source study/constraint new regime wherever experimentally accessible explore possible new detection channels R&D Projects
Kuo-Sheng Nuclear Power Plant KS NPS-II : 2 cores 2.9 GW KS Lab: 28 m from core#1
Kuo Sheng Reactor Neutrino Laboratory Front Gate Configuration: Modest yet Unique Flexible Design: Allows different detectors conf. for different physics Inner Target Volume Front View (cosmic vetos, shieldings, control room …..)
R&D Projects Explore New Detectors Scenarios (LE, 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) 1 st goal : sensitivity of 10 -14 g/g in 40 K Sono-Luminescence Project (inter-disciplinary)
Kuo-Sheng + Wan-Li Site Geographically possible for medium baseline experiment for “ 13 ” Merits / Our Offer : Easy reach from city Access to Plant established Road tunnel at 2 km 100 m rock overburden Contacts with International Team
Date: Wed, 21 May 2003 16:36:25 +0800 (CST) From: Henry Tsz-king Wong To: ………………………. Subject: Re: Future Reactor ExperimentsHenry Tsz-king Wong …….. We are aware of this possibility and have discussed a bit among ourselves. Our thinking is that we will not just "go out and do the experiment ourselves." (we are busy with ongoing things, and the required resources will be beyond what we can have on our own). However, if there would be an international team who would bring in a strong scientific case and substantial resources, we would be interested to explore the scenario of performing such an experiment in Taiwan. A 1% measurement of the reactor spectra is very tricky, and I agree that having too many cores may not be a positive aspect. ……………. TEXONO’s standpoint/position ::
Possibility and Offer Raised to International Study Group : …. a 140 page document !!!
"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.
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.
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.
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).
Taiwan Experimental Particle Physics a small & 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 ( ) More topics under way Diversified R&D Program in parallel Reactor 13 experiment : Kuo-Sheng Plant+Wan-Li Tunnel submitted for consideration Our hands are tight, but we keep our mind, eyes & heart open Summary & Outlook
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 Some Personal Thoughts : (forgive me if I am incorrect)
