  1. HES HKS meeting Lady justice 14/Apr/2011 T.Gogami 2/Apr/2011, Frankfurt, Germany

  2. Itinerary Analysis (Tracking) • Newport News, US (JLab) • 2/01 Narita  US • 2/27-28 HES HKS collaboration meeting, 4th JSPS core to core meeting • 3/11Norfolk  Washington D.C. • The Great earthquake news when I woke up! • 3/12 Washington D.C  Frankfurt • Mainz, Germany (Mainz Univ.) • 3/17-18 KaOS meeting in Mainz • Extend to stay in Germany ( 3/214/4 ) • Darmstadt, Germany (GSI) • 3/30 – 4/4 • 4/4 Frankfurt  Narita • Fukushima, Japan • Tokyo(4/5)  Fukushima(4/6) • Sendai, Japan • Fukushima(4/11)  Sendai(4/11) Analysis (Rate , Efficiency), JPS Analysis code , Shift , cabling Meeting, Inside GSI

  3. Contents • KTOF TDC cut test • KDC layer rates output

  4. KDC hit wire selection code KDC1 KDC2 • GREEN regionSelective region • RED markers & linesSelected hit wires • BLACK markers & lines Rejected hit wires

  5. KTOF TDC • Cut 10000 – 50000 (current) 18000 – 20500 (test) Run 76314 for CH2 target Run 77124 for 52Cr target

  6. Results after KTOF TDC cut 2.0 [μA] , CH2 , 76315 7.6 [μA] , 52Cr , 77124 • After TDC cut  Error • Analysis time ~20% reduction

  7. KTOF TDC • Cur Region 2100 – 2400 (Accidental) 2600 – 2800 (signal) Run 76314 for CH2 target Run 77124 for 52Cr target

  8. KDC DC Efficiency Rate

  9. KDC Rate vs. Efficiency • Looks two tendencies • Applied voltages ? • Threshold ? Need to check Run sheet

  10. Summary and to do • Summary • KTOF TDC cut • No bad effects for Number of Kaon • Analysis time is faster • Check sub peaks • Rate vs. Efficiency of KDC • Two tendencies  Check KDC applied voltage and threshold • To do • HES • Tracking • Efficiency, Rate • E01-011 • 授業料免除 • RA • 学振 • 5/6 ----- 8/1 Germany • あと3週間で出発！

  11. End 31/Mar/2011, Darmstadt, Germany
