The Res_monitor Component

Monitor for resolution calculations

Identification

• Site:
• Author: Kristian Nielsen
• Origin: Risoe
• Date: 1999

Description

A single detector/monitor, used together with the Res_sample component to
compute instrument resolution functions. Outputs a list of neutron
scattering events in the sample along with their intensities in the
detector. The output file may be analyzed with the mcresplot front-end.

Example: Res_monitor(filename="Output.res", res_sample_comp=RSample, xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1)

Setting the monitor geometry.
The optional parameter 'options' may be set as a string with the
following keywords. Default is rectangular ('square'):
box                       Box of size xwidth, yheight, zdepth
cylinder                  To get a cylindrical monitor (diameter is xwidth, height is yheight).
banana                    Same as cylinder, without top/bottom, on restricted angular area
disk                      Disk flat xy monitor. diameter is xwidth.
sphrere                   To get a spherical monitor (e.g. a 4PI) (diameter is xwidth).
square                    Square flat xy monitor (xwidth, yheight)

Input parameters

Parameters in boldface are required; the others are optional.
