2 Captures on Gd GADZOOKS! project Identify n ē p events by neutron tagging with Gadolinium in SK. Gadolinium has large neutron capture cross section and emit 8MeV gamma cascade. n e p e + n Gd 8 MeV ΔT~30μs Vertices within 50cm Physics targets: (1) Supernova relic neutrino (SRN) (2) Improve pointing accuracy for galactic supernova (3) Precursor of nearby supernova by Si-burning neutrinos (4) Reduce proton decay background (5) Neutrino/anti-neutrino discrimination (6) Reactor neutrinos γ Gadolinium Antineutrino Detector Zealously Outperforming Old Kamiokande, Super!

3 Supernova Relic Neutrino (SRN) NOW Neutrinos from past SNe 1billion years ago 10 billion years ago Beginning of the universe S.Ando, Astrophys.J. 607, 20(2004) 3 Theoretical flux prediction : 0.3~1.5 /cm2/s (17.3MeV threshold)
4 Supernova Relic Neutrino (SRN) NOW Neutrinos from past SNe First goal is discovery of SRN 1billion years ago 10 billion years ago Beginning of the universe S.Ando, Astrophys.J. 607, 20(2004) 4 Theoretical flux prediction : 0.3~1.5 /cm2/s (17.3MeV threshold)
5 Search for SRN at Super-K Search window for SRN at SK : From ~10MeV to ~30MeV Now SRN search is limited by BG. We need BG reduction by the neutron tagging which can be achieved by GADZOOKS! 5
6 6 EGADS Evaluating Gadolinium s Action on Detector Systems 200 m 3 tank with 240 PMTs Transparency measurement (UDEAL) 15m 3 tank to dissolve Gd Gd water circulation system (purify water with Gd)
7 EGADS detector: Baby-Kamiokande One of main goals for EGADS is to study the Gd water quality with actual detector materials. Thus, the detector fully mimic Super-K detector. : SUS frame, PMT and PMT case, black sheets, etc. Gd dissolving test has been performed since Oct (see next page) 7
8 Transparency of Gd water with PMTs The light left at 15 m in the 200m 3 tank was ~75% for 0.2% Gd 2 (SO 4 ) 3, which corresponds to ~92% of SK-IV pure water average. 8
9 Where we are now? Now, we are summarizing the R&D results and making a proposal. A committee which was formed to review and evaluate the proposal has started the review. After the review of the committee, we will start collaboration wide discussion in this June. If the proposal is approved, more detailed plan will be made also with T2K members. 9
10 Summary GADZOOKS! is a project to upgrade Super-K, so that SRN ν ē can be tagged by the delayed coincidence signal from a neutron capture of Gd. EGADS detector was build for R&D of Gd water purification system and check Gd effect to Super-K. EGADS has been keeping a good water quality with the target Gd concentration after PMT installation. Collaboration wide discussion to decide the Gd installation to Super-K will start in June (two weeks). 10
11 Improvement for Proton decay Neutron multiplicity for P e + p 0 MC 92.5% Zero n Atmospheric n BG Accompany many n If one proton decay event is observed at Super-K after 10 years Current background level: 0.58 events/10 years Background with neutron anti-tag: events/10 years Background probability will be decreased from 44% to 9%. 11

Also, it enables us to extract n e + n x spectrum.
