  • 10:01am, in chamber, balanced
  • 10:03am, roughing pump on
  • 10:23am, turbo pump on
  • 12:16pm excitation (3kV, ~20s), quiet time before 1162844853, quiet time after 1162844912.
    • This was lost because the frame disk was full and the wiper.pl script was not running!!! The crontab was pointing to x1 instead of x3
    • I deleted some old frame files and updated the crontab. The problem should be fixed now
  • 1:50pm, excitation (3kV, ~30s), quiet time before 1162850776, quiet time after 1162850868
  • 2:50pm, excitation (1.9kV, ~30s), quiet time before 1162853341, quiet time after 1162853481
