[mcstas-users] adjusted dist, xw and yh

[wokaoyan1981]

Hello Aaron,




Thank you for your wonderful suggestions. I delete components behind collimator 1 and set a series of  monitors instead . Parameters dist, xw and yh are set as the following:

1: xw=0.06m、yh=0.11m、dist=2.000m（prototype）;

2: xw=0.08m、yh=0.13m、dist=2.000m;

3: xw=0.08m、yh=0.13m、dist=4.049m (focusing to the M2Exit slit)；

4: xw=0.08m、yh=0.13m、dist=10.649m (focusing to the end of the collimator1)；




The simulation suggests: N increases remarkably while ERR decreases. 





I don’t know which project to choose since the results differ in neutron intenstiy, divergence and distribution. See I, y_div, x_I in enclosure.
