Detector options for Rapid Access / Mail-In Users:
All values are calculated for our area detectors at a wavelength of lambda = 0.2076 Angström.
PXRD measurements - Option 1:
The area detector will be in the centered configuration and placed at a distance of 1000 mm.
| Information content | Q (1/Angström) | Q_min (1/Angström) | 2Theta at 0.2076 Angström | comparable 2Theta in CuKalpha1 radiation |
|---|---|---|---|---|
| Full Debye-Scherrer ring | ~ 6.1 | ~ 0.1 | ~ 11.59° | ~ 97° |
| Corner position on detector | ~ 8.5 | ~ 0.1 | ~ 16.1° | - |

PXRD measurements - Option 2:
The area detector will be off-centered to the corner position of the detector and placed at a distance of 2300 mm.
Please be aware that in this configuration due to the large distance, air scattering will become more severe.
| Information content | Q (1/Angström) | Q_min (1/Angström) | 2Theta at 0.2076 Angström | comparable 2Theta in CuKalpha1 radiation |
|---|---|---|---|---|
| Quarter Debye-Scherrer ring | ~ 5.3 | ~ 0.1 | ~ 10.1° | ~ 81.5° |
| Corner position on detector | ~ 7.6 | ~ 0.1 | ~ 14.1° | ~ 132° |

Total Scattering/PDF measurements - Option 3:
The area detector will be in the centered configuration and placed at a distance of 280 mm.
| Information content | Q (1/Angström) | Q_min (1/Angström) | 2Theta at 0.2076 Angström | comparable 2Theta in CuKalpha1 radiation |
|---|---|---|---|---|
| Quarter Debye-Scherrer ring | ~ 18.8 | ~ 0.25 | ~ 36.2° | - |
