Description
A simple beamline setup consisting of a single focusing mirror, a monochromator, and a four-circle goniometer at the sample stage.
Input parameters
Parameters in boldface are required; the others are optional.| Name | Unit | Description | Default |

| phi_mirror | m | Set angle of incidence of the focusing mirror | 3 |
| phi_mono | deg | Set angle of incidence of Monochromator crystal. | 9.25 |
| chi | deg | 2nd rotation of four circle, around X. | 0 |
| ome | deg | 1st rotation of four circle, around Y. | 0 |
| phi | deg | 3rd rotation of four circle, around Y'. | 0 |
| tth | deg | 4th rotation of four circle, i.e. detector arm. Around Y. | 0 |
| dphi | deg | Restrict the powder scattering angle along vertical axis Z. | 160 |
