We now want to replace the <tt>PSD_monitor</tt> with a model of the DMC detector which has 400 channels with a 0.2\(^\circ\) spacing, each 0.1 m tall. It is often run in two settings, 0.1\(^{\circ}\) apart. In this way the effective angular spacing between adjacent channels is 0.1\(^{\circ}\), and the distance between detector channels 1 and 800 is 79.9\(^\circ\). The detector can rotate around the sample until the highest detector channel is at approx. 140\(^\circ\). In McStas, this detector can be inserted by means of <tt>Monitor_nD</tt> with input parameters (exactly)

options = "banana, theta bins=800 limits=[20 100]",
xwidth = 2, yheight = 0.1, filename = "My_datafile"

Test the new detector set-up. Simulate incoherent background counts in all detector channels e.g. by exchanging the <tt>Powder1</tt> sample for a <tt>V_sample</tt> component of same size. Then put back the <tt>Powder1</tt> sample and the vary the collimation of the incoming beam to see how this affects the powder signal.
