  • Normal check (1/10)
  • Linearity of the PMT gain
  • dark noise rate
  • charge resolution
  • Golden PMTs (1/60)
  • normal check
  • 2D sensitivity scan
  • Absolute calibration
  • makes all PMTs
  • assembles DOMs
  • check all DOMs
  • (under low temperature)
  • Linearity of the DOM gain
  • dark noise rate
  • component check
  • cold reboot
  • communication test
  • Golden DOMs (1/80)
  • 2D sensitivity scan
  • Absolute calibration
