Collimator_linear Component
Soller collimator with rectangular opening and specified length. The
transmission function is an average and does not utilize knowledge of the
actual neutron trajectory. A zero divergence disables collimation (then the
component works as a double slit).
Example: Collimator_linear(xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1,
len=0.25, divergence=40,transmission=0.7)
| Name | Unit | Description | Default |
|---|---|---|---|
| xmin | m | Lower x bound on slits | 0 |
| xmax | m | Upper x bound on slits | 0 |
| ymin | m | Lower y bound on slits | 0 |
| ymax | m | Upper y bound on slits | 0 |
| xwidth | m | Width of slits | 0 |
| yheight | m | Height of slits | 0 |
| len | m | Distance between slits | |
| divergence | minutes of arc | Divergence horizontal angle (calculated as atan(d/len), where d is the blade spacing) | 40 |
| transmission | 1 | Transmission of Soller (0<=t<=1) | 1 |
| divergenceV | minutes of arc | Divergence vertical angle | 0 |
