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

  • Take photos of green sheet with blocks1 starting from big field size to small
  • Take photo of discolouration
  • Take out blocks1 and photo with colorchecker
  • Put in blocks2 and blue enhanced scint sheet – repeat
  • Remove blue sheet – repeat measurements
  • Photo blocks1 and colorchecker again
