In this problem, you should optimize your instrument with respect to intensity and/or \(q\)-resolution. Anything goes as long as it works.
The DMC instrument will be upgraded over the next few years, and you may be able to find a suggestion for improvement that is better than the planned. Perhaps you can save PSI a few million Swiss Francs?
The best instrument is the one that gives the best results in terms of intensity and resolution combined. A good figure-of-merit could be peak intensity squared divided by peak width (and it is not allowed to increase the structure factor).
It may be possible to optimize guide parameters and geometry, monochromator parameters and geometry, distances, collimations, detector dimensions. Note that McStas has a built-in optimizer function. The details of this is best explained in the class.
