Simulation Project tripleaxis: Collimator

Insert a linear collimator between monochromator and sample. The collimation should be 80' in the horizontal direction; open vertically. A typical dimension is 10 cm width, 20 cm height, and 20 cm length. Simulate the intensity, divergence and energy distribution (in particular: the energy width) at the sample position for 5.0 meV neutrons and focusing monochromator. Try also a 40' and a 20' horizontal collimator. Compare to the situation without collimation and comment on the results.

From now on, use a 80' horizontal collimator.
