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(nh=20, ndiv=20, filename="Output.dip", xwidth=0.1, yheight=0.1, maxdiv_h=2)
Input parameters
Parameters in boldface are required; the others are optional.| Name | Unit | Description | Default | |
| nh | 1 | Number of bins in position | 20 | |
| ndiv | 1 | Number of bins in divergence | 20 | |
| filename | str | Name of file in which to store the detector image | 0 | |
| xwidth | m | Width of detector. | 0.1 | |
| yheight | m | Height of detector. | 0.1 | |
| maxdiv_h | deg | Maximal horizontal divergence detected | 2 | |
| restore_xray | 1 | If set, the monitor does not influence the photon state | 0 | |
| nx | 1 | Vector definition of "forward" direction wrt. divergence, to be used e.g. when the monitor is rotated into the horizontal plane | 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 | Vector definition of "forward" direction wrt. divergence, to be used e.g. when the monitor is rotated into the horizontal plane | 1 | |
| nowritefile | 1 | If set, monitor will skip writing to disk. | 0 |
