DivPos_monitor
Component2D 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", xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1, maxdiv_h=2)
Name | Unit | Description | Default |
nh | 1 | Number of bins in position. | 20 |
ndiv | 1 | Number of bins in divergence. | 20 |
filename | Name of file in which to store the detector image. | 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 | deg. | Maximal horizontal divergence detected. | 2 |
restore_xray | 1 | If set, the monitor does not influence the photon state. | 0 |
nx | 1 | 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 | 1 | |
nowritefile | 1 | If set, monitor will skip writing to disk. | 0 |
