Union_logger_2D_space ComponentPart of the Union components, a set of components that work together and thus sperates geometry and physics within McStas. The use of this component requires other components to be used. 1) One specifies a number of processes using process components 2) These are gathered into material definitions using Union_make_material 3) Geometries are placed using Union_box/cylinder/sphere, assigned a material 4) A Union_master component placed after all of the above Only in step 4 will any simulation happen, and per default all geometries defined before this master, but after the previous will be simulated here. There is a dedicated manual available for the Union_components This logger logs a 2D projection of the position of each scattering in the lab frame. This logger needs to be placed in space, the position is the center of the histogram. A logger will log something for scattering events happening to certain volumes, which are specified in the target_geometry string. By leaving it blank, all geometries are logged, even the ones not defined at this point in the instrument file. If a list og target_geometries is selected, one can further narrow the events logged by providing a list of process names in target_process which need to correspond with names of defined Union_process components. To use the logger_conditional_extend function, set it to some integer value n and make and extend section to the master component that runs the geometry. In this extend function, logger_conditional_extend[n] is 1 if the conditional stack evaluated to true, 0 if not. This way one can check what rays is logged using regular McStas monitors. Only works if a conditional is applied to this logger.
| Name | Unit | Description | Default | |
| target_geometry | string | Comma seperated list of geometry names that will be logged, leave empty for all volumes (even not defined yet) | "NULL" | |
| target_process | string | Comma seperated names of physical processes, if volumes are selected, one can select Union_process names | "NULL" | |
| D_direction_1 | string | Direction for first axis ("x", "y" or "z") | "x" | |
| D1_min | m | Histogram boundery, min position value for first axis | -5 | |
| D1_max | m | Histogram boundery, max position value for first axis | 5 | |
| n1 | 1 | Number of bins for first axis | 90 | |
| D_direction_2 | string | Direction for second axis ("x", "y" or "z") | "z" | |
| D2_min | m | Histogram boundery, min position value for second axis | -5 | |
| D2_max | m | Histogram boundery, max position value for second axis | 5 | |
| n2 | 1 | Number of bins for second axis | 90 | |
| filename | string | Filename of produced data file | "NULL" | |
| order_total | 1 | Only log rays that scatter for the n'th time, 0 for all orders | 0 | |
| order_volume | 1 | Only log rays that scatter for the n'th time in the same geometry | 0 | |
| order_volume_process | 1 | Only log rays that scatter for the n'th time in the same geometry, using the same process | 0 | |
| logger_conditional_extend_index | 1 | If a conditional is used with this logger, the result of each conditional calculation can be made available in extend as a array called "logger_conditional_extend", and one would then acces logger_conditional_extend[n] if logger_conditional_extend_index is set to n | -1 | |
| init | string | Name of Union_init component (typically "init", default) | "init" |
| AT ( | , | , | ) RELATIVE | |||
