Analysis and Itinerary of HES/HKS Meeting in Germany and Japan: Focus on KTOF TDC Efficiency

This document outlines the itinerary and meeting agenda for T. Gogami's travels across Germany and Japan in April 2011. It includes details of collaboration meetings, significant events such as The Great Earthquake news, and various analytical sessions focusing on KTOF TDC cut tests and KDC efficiency rates. Key findings and future tasks related to rate and efficiency analyses are summarized, highlighting trends observed in experimental data. The timeline specifies travel routes and locations including Frankfurt, Mainz, and Fukushima.

  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
