Also, add an angle to rotate the part of the instrument located after the sample, e.g. TT (Two $\Theta$) and decide a more relevant size of the now rectangular detector. Look at your results from the last simulation to determine an approximate scan range for the OM angle. Also, set a small focus_r on the sample component to minimize calculation time on non-detected neutrons. Scan OM across the powder lines. Between sample and detector, set up an analyser crystal by copying and modifying your monochromator component. (Add new arms and angles OMA, TTA - A is for Analyzer - for adjusment.) Adjust the analyser to Bragg condition for the chosen wavelength. Re-scan TT and notice the difference to the scan performed in the previous task. Try also scanning around -TT and notice the difference to the other scan. Printable version Last Modified: Tuesday, 22-Jun-2004 14:04:14 CEST
