  1. RPC TC/RC/DPG/Commissioning meeting at 18.aug.2014 Dong-hyunkim Behalf on the RPC current investigate team

  2. Plan • RPC Current study at P5 – Part : RPC EN4 all channels

  3. Step 1 • 1. Research the EN4 part 36 channel( From 20.May To 21.May )

  4. Step 1 • 1. Research the EN4 part 36 channel( From 20.May To 21.May )

  5. Step 1 • 1. Research the EN4 part 36 channel( From 20.May To 21.May )

  6. Step 1 • 1. Research the EN4 part 36 channel( From 20.May To 21.May )

  7. Step 1 • 1. Research the EN4 part 36 channel( From 20.May To 21.May )

  8. Step 1 • 1. Research the EN4 part 36 channel( From 20.May To 21.May )

  9. Step 2 • 2. Select channel that had a potential problem Current all most Zero Unstable

  10. Step 2 • 2. Select channel that had a potential problem Current all most Zero Unstable current at 9400V

  11. Step 2 • 2. Select channel that had a potential problem Current almost Zero Current goes down to Zero

  12. Step 3 • 3. Select research period( common period from May to Aug. )

  13. Step 4 • 4. Investigate channels that had potential problem( Processing ) < EN4 R2_R3_C10 Low – current > • < EN4 R2_R3_C06 current down to ≈ 0 > • Several channels had this pattern • 7.03 14~ 7.04 21-9400 • 8.01 12~8.03 17-9400

  14. Conclusion • Ongoing to investigate for the EN4 potential problem channels. • Continuously, we will investigate the EP4 36 channels
