The DivPos_monitor Component
Divergence/position monitor (acceptance diagram).
Identification
- Author: Kristian Nielsen
- Origin: Risoe
- Date: 1999
- Version: 1.19
Description
2D detector for intensity as a function of both horizontal position
and wavelength. This gives information similar to an aceptance diagram used
eg. to investigate beam profiles in neutron guides.
Example: DivPos_monitor(npos=20, ndiv=20, filename="Output.dip",
xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1, maxdiv=2)
Input parameters
Parameters in boldface are required; the others are optional.| Name | Unit | Description | Default |
|---|---|---|---|
| npos | 1 | Number of bins in position | 20 |
| ndiv | 1 | Number of bins in divergence | 20 |
| filename | string | Name of file in which to store the detector image | |
| restore_neutron | 1 | If set, the monitor does not influence the neutron state | 0 |
| xmin | m | Lower x bound of detector opening | 0 |
| xmax | m | Upper x bound of detector opening | 0 |
| ymin | m | Lower y bound of detector opening | 0 |
| ymax | m | Upper y bound of detector opening | 0 |
| xwidth | m | Width/diameter of detector (x). Overrides xmin,xmax. | 0 |
| yheight | m | Height of detector (y). Overrides ymin,ymax. | 0 |
| maxdiv | degrees | Maximal horizontal divergence detected | 2 |
Output parameters
| Name | Unit | Description | Default |
|---|---|---|---|
| Div_N | - | Array of neutron counts | |
| Div_p | - | Array of neutron weight counts | |
| Div_p2 | - | Array of second moments |
