Sample Transfer and Measurement Positions
- Ensure the X-ray source is off and pulled out to the safe position marked by the top red line on the linear transfer.
X-ray source position for sample transfer |
- Transfer the sample.
- Move the manipulator to the default position for XPS:
Theta angle | 240° |
x | 25.0 |
y | 28.0 |
z | 10.0 |
- Verify sample position in camera view. Orange circle indicates analyzed area (~7 mm).
Analyzed area |
- Adjust Z-axis (vertical) position.
-
Adjust horizontal position.
- X and Y must be moved almost simultaneosly. Change each single axis by no more than 1 mm.
- Per 1 mm of horizontal asjustment, move Y by 0.87 mm (sin(60°)) and X by -0.5 mm (-cos(60°)).
Δd (mm) | X (mm) | Y (mm) | Δd (mm) | X | Y | |
0 | 25.0 | 28.0 | Default position | 0 | 25.0 | 28.0 |
-1 | 24.5 | 28.9 | 1 | 25.5 | 27.1 | |
-2 | 24.0 | 29.7 | 2 | 26.0 | 26.3 | |
-3 | 23.5 | 30.6 | 3 | 26.5 | 25.4 | |
-4 | 23.0 | 31.5 | 4 | 27.0 | 24.5 | |
-5 | 22.5 | 32.3 | 5 | 27.5 | 23.7 |
- Lower X-ray gun to the red line on the linear transfer, approximately 8 mm from the bottom limit. (8 mm equals the width of wrench 7, which is often somewhere around.)
