Template_Johann_spec InstrumentThis is a template instrument for a Johann spectrometer intended for easy inclusion in other "real" instrument simulations. The source is a divergent line like source which illumnates the full crystal. The analyzer crystal itself is modelled as a single bent crystal curved to a primary radius of 2*Rowland-radius. To include a Johann spectrometer in an instrument the sample should be put where source is in this template. and otherwis copy-paste.
| Name | Unit | Description | Default |
| L | m | Length of the analyzer crystal. | 0.2 |
| r_Row | m | Radius of the Rowland circle. Also governs the crystal curvature (2*r_Row). | 0.5 |
| theta_inc | deg | Angle of incidence at the crystal centre | 78.5 |
| dtheta_s | deg | Rotation angle of the Source. To allow scanning with a pencil beam across the crystal face. | 0 |
| phi_s | deg | Opening angle of source. If 0 it is set to cover the full crystal (and some). | 0 |
