XPcal hammering test

[Sawada, DanChen, Darkhan, Yokozawa, Washimi]

We performed the hammering test for the X-end PCal.
diaggui files are recorded in /users/PEM/Hammering_boeforeO4/XPCal_20200929/

Step 1 : Hammering by hand or foot with monitoring the Rx PD to find some interested points.

  • 10:51 EXA_tsuurogawa.xml [plot]
  • 10:53 EXA_leg.xml [plot]
  • 10:53 EXA_leg_berrows.xml [plot]
  • 10:55 Viewport_Rx.xml [plot]
  • 10:56 Rx_leg.xml [plot]
  • 10:57 Viewport_Tx.xml [plot]

  • 11:00 ground.xml [plot]
  • 11:01 Sound.xml [plot]
  • 11:02 Al-hoil,xml [plot]

Step 2 : Location ghe 4 portable accelerometers.

  • K1:PEM-PORTABLE_EXA_BOOTH_EXA_BNC4_OUT  : Impact hammer
  • K1:PEM-PORTABLE_EXA_BOOTH_EXA_BNC5_OUT  : ACC on the ground (berrows leg) [photo]
  • K1:PEM-PORTABLE_EXA_BOOTH_EXA_BNC6_OUT  : ACC on the in-vacuum table [photo]
  • K1:PEM-PORTABLE_EXA_BOOTH_EXA_BNC7_OUT  : ACC on the viewport for Tx [photo]
  • K1:PEM-PORTABLE_EXA_BOOTH_EXA_BNC8_OUT  : ACC on the viewport for Rx [photo]

Step 3 : Hammering test by the impact hammer

  • 11:46 impact_viewport_Rx.xml [plot]
  • 11:47 impact_Rx.xml [plot]
  • 11:48 impact_Tx.xml [plot]

Step 3 : Shaker injection (white noise)

  • 11:54 shaker_viewport_Rx.xml [plot]
  • 11:55 shaker_EXA_tsuurogawa.xml [plot]
  • 11:56 shaker_Rx.xml [plot]
  • 11:57 shaker_Tx.xml [plot]

Step 4 : FFU off
