Question
What kind of data are needed for Giraffe WET calibration?
Answer
We need the water tank reference measurement and Giraffe reference measurement as below:
Water tank reference measurement:
- Using the correct chamber
- Suggested to use Gantry 0°
- Water depth should be enough for the highest energy
- Notice the WET of chamber‘s entrance window
- At least 6 different energies
Giraffe reference measurement:
- Gantry 90° or 270°
- Remove the 1mm plastic protection foil
- Use the Dummy_calibration.csv as calibration file (you can find it in installer CD, or you can download it here below. Please edit the SN first)
- Do not run any uniformity calibration before measurement
- Please apply background measurement
- Apply the same ranges used for water tank reference data (same energies, same nozzel, etc)
