3.1.1 Basic Setup (Bragg-Brentano, dedicated and TWIN / TRIO Optics)
The basic reference position of the D8 system is set in Bragg-Brentano geometry at factory.
This must finally be done/checked in the Configuration plugin of the MEASUREMENT
SUITE:
1. Theta-Theta: MotorizedDrives/Inner_Circle_Motor | Reference Position according
Acceptance Test Protocol
2. Theta-2Theta: MotorizedDrives/Outer_Circle_Motor | Reference Position according
Acceptance Test Protocol
3. This Reference Position must be saved to data base of the MEASUREMENT SUITE by
the Save configuration to data base of the Configuration plugin.
´ The software will ask for a name for this configuration. The name is Instrument
Verification Factory.
4. Save and activate this setting.
3.1.2 Additional Setups (Göbel Mirror, Parallel Beam TWIN / TRIO Optics)
Additional setups like different parallel beam setups with Göbel mirrors or the parallel beam
path of the TWIN / TRIO optics have beam directions different from the basic Bragg-Brentano
setup. Accordingly, this information must be added to the data base. The system takes this
into account by the deflection angles of the optics. The value of the deflection angle is identi-
cal for theta-theta and theta-2theta systems. This must finally be done/checked in the Con-
figuration plugin of the MEASUREMENT SUITE:
1. Göbel mirror: Goniometer/PrimaryTrack/GoebelMirror | Deflection angle according
Acceptance Test Protocol
2. TWIN optics: Goniometer/PrimaryTrack/TWIN OPTICS/GoebelMirror| Deflection
angle according Acceptance Test Protocol
TRIO optics: Goniometer/PrimaryTrack/TRIO OPTICS/GoebelMirror| Deflection
angle according Acceptance Test Protocol
