  1. Summary of Various Parameters on Gd-LS  주경광(전남대) • 검출기 사이즈 비교 • 여러 solvent 특성 비교 • Cost estimation • LAB R&D 비교 • Ligand 사용양 • Radiopurity & Single rates • 기타 7th RENO Collaboration Meeting @SNU 2007-12-21

  2. 각 실험 검출기 크기 비교

  3. 여러 Solvent에 대한 일반적 성질

  4. 여러 배합과 사용시 문제점들 • Palo Verde: PC(40%)MO(60%)PPO(3g/l)bisMSB(50mg/l) +Gd(1g/l) • Double Chooz: PXE(20%)Dod(80%)PPO(3g/l)bisMSB(50mg/l) +Gd(1g/l) • Daya Bay: PC(20%)Dod(80%)PPO(3g/l)bisMSB(50mg) + Gd(1g/l) • RENO R&D: LAB(100%)PPO(3g/l)bisMSB(50mg/l) + Gd(1g/l)

  5. Solvent 정제 결과 • Borexino: PXE(4.4m, Koch company, USA 제품) RENO (Fisher, 일본산) • BNL: LAB의 attenuation length ~20m (Petresa 제품)

  6. Cost Estimation

  7. Gd Powder Issue Radiopurity • Gd2O3: U/Th concentrations are lower than 2x10-10 g/g and 3x10-10g/g • The concentrations of some others elements are: Pb: 1.4x10-6g/g Er: 1.5x10-7g/g Ho: 1.1x10-7g/g Dy: 1.5x10-6g/g Eu: 2.1x10-7g/g Sm: 7.6x10-8g/g Nd: 3.3x10-8g/g Pr: 3.8x10-9g/g La: 2.3x10-7g/g • The concentrations of the others elements are lower of limits of identifications

  8. LAB R&D 결과

  9. NIM-A 2007.09.044 Summary of Daya Bay paper

  10. GdR3 + Ligand 사용량

  11. (공대정박사) Radiopurity & Single rates between different Experiments
