The Divergence_monitor Component
Based on neutron component by Kim Lefmann
Horizontal+vertical divergence monitor.
Identification
- Author: Erik B Knudsen
- Origin: DTU Physics
- Date: Jun. '16
- Version: $Revision$
Description
A divergence sensitive monitor. The counts are distributed in
(n times m) pixels.
Example: Divergence_monitor(nh=20, nv=20, filename="Output.pos",
xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1,
maxdiv_h=2, maxdiv_v=2)
Input parameters
Parameters in boldface are required; the others are optional.| Name | Unit | Description | Default |
|---|---|---|---|
| nh | 1 | Number of pixel rows | 20 |
| nv | 1 | Number of pixel columns | 20 |
| rad | 1 | If set - divergence will be measured in radians. | 0 |
| filename | 0 | ||
| xmin | m | Lower x bound of detector opening | -0.05 |
| xmax | m | Upper x bound of detector opening | 0.05 |
| ymin | m | Lower y bound of detector opening | -0.05 |
| ymax | m | Upper y bound of detector opening | 0.05 |
| xwidth | m | Width of detector. Overrides xmin, xmax | 0 |
| yheight | m | Height of detector. Overrides ymin, ymax | 0 |
| maxdiv_h | degrees | Maximal horizontal divergence detected | 1 |
| maxdiv_v | degrees | Maximal vertical divergence detected | 1 |
| restore_xray | 1 | If set, the monitor does not influence the photon state | 0 |
| nx | 0 | ||
| ny | 1 | Vector definition of "forward" direction wrt. divergence, to be used e.g. when the monitor is rotated into the horizontal plane | 0 |
| nz | 1 | ||
| nowritefile | 1 | If set, monitor will skip writing to disk | 0 |
Output parameters
| Name | Unit | Description | Default |
|---|---|---|---|
| Div_N | - | Array of photon ray counts | |
| Div_p | - | Array of photon weight counts | |
| Div_p2 | - | Array of second moments |
