Collimator_linear
ComponentSoller 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 |
