Third experimental measurements with Cyberknife at Birmingham. Green and blue scintillator thin sheet measurements with measurements of green radiation damage.

Setup

Camera settings

  • Focal length 20mm
  • lens focus distance – 0.5 (500mm)
  • 53cm focal plane (phi on camera ) to sheet
  • f-number 5.6

Plan
