  • 9:39am, in chamber, balanced
  • 9:39am, roughing pump on
  • 9:52, turbo pump on
  • 12:14pm, excitation: first band passed around 1100 Hz (using filter bank FM5) with amplitude 3kV, then usual broadband with amplitude 3 kV
    • quiet time after 1163016908
  • 2:50pm, excitation as above, quiet time before  1163026243, quiet time after 1163026429
  • 3:28pm, the previous excitations didn't work very well, done anothe one. Quiet time after 1163028556
  • 7:09pm, another excitation (3kV, 30s). Quiet time before 1163041791, quiet time after 1163041952. This is good
  • 9:04pm, another excitation (3kV, 60s). Quiet time before 1163048623, quiet time after 1163048849
