Description
A component that optimizes the neutron flux passing through the Source_Optimizer in order to have the maximum flux at the Monitor_Optimizer position(s). Source_optimizer should be placed just after the source. Monitor_Optimizer should be placed at the position to optimize. I prefer to put one just before the sample.
See Source_Optimizer for usage example and additional informations.
Input parameters
Parameters in boldface are required; the others are optional.

Optimization locations for the Source_Optimizer
The Monitor_Optimizer component works with the Source_Optimizer component. See section 3.8 for usage.
The input parameters for Monitor_Optimizer are the rectangular shaped opening coordinates \(x_{min}\), \(x_{max}\), \(y_{min}\), \(y_{max}\), and the name of the associated instance of Source_Optimizer used in the instrument description file (one word, without quotes).
As many Monitor_Optimizer instances as required may be used in an instrument, for possibly more than one optimization location. Multiple instances may all have an effect on the total intensity.
