Congwu,
I'm getting confused with the units of your diffraction patterns, could
you just indicate 2theta which is probably the primary observation
without any assumption about lambda?
Also, I've trouble with your simulated Si pattern: there should be no
traces of Zr radiation generated peaks,
... The problems bothering me are
the measured peak is much wider than the simulation
Peak widths should be 400 microns (your beamsize) divided by 3.5 cm
(your distance) in radians, which is about 180*0.4/3.5/PI = 6.5 degrees.
HTH,
Jon
Dear Congwu,
as you put it, it definitely seems that you don't get out the MoK
radiation from your collimator. Control the alignment and make sure
the beam hits your sample.

Hi, Miguel, the unit is the so-called moment transfer
