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

- 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
