<P>Here is Mr. Saed Almomani from KAERI, I'm working on conceptual design of HRPD for the Jordan Research & Training Reactor JRTR. I'm using McStas software to test and verify my design, and when I used the Si.laz sample in my code I found that some of reflection planes are not shown in the diffraction pattern such as (220) !! then I tried to use D2B HRPD code (built-in McStas) to test the Si.laz sample and the problem was the same " the 220 reflection plane was not shown" !! then I tried to use the Al.laz sample and I got a perfect diffraction pattern !<BR>So what is the problem and why is that ? is there any error in the (Si.laz) predefined sample of McStas ? and what is the best way to solve this problem? </P>
<P> </P>
<P>Thank you in advance <BR><BR><BR></P>
