HLS Water Levels

• I reported on MINOS and Aurora mine water level
  data
• Many light sources use water levels to set
  alignment of their machines
• A Medvedko from Budker reported on ultra sonic
  water levels

Other Accelerators

• There are 50 light sources in operation,
  construction or planning
• Energy range 2.5 to 3.5 Gev with x rays 10 to 100
  Kev
• NIST has a calibration standard for laser
  trackers and offers a calibration service
