I find myself struggling to understand some questions relating to synchrotron xray diffraction. The first question goes as follows:
What are the advantages of using relatively high energy X-rays (λ=0.5Å) as available at the synchrotron over using a conventional Cu X-ray source (λ=1.5406Å)?
The only advantages that I know of include:
(1) Gives a higher resolution due to synchrotron being orders of magnitudes brighter than other conventional sources which leads to do quick experiments even on small samples.
(2) It has a longer spectrum ranging from infrared to hard x-rays.
But I feel like my answers are not quite enough to answer the question yet.
Second question goes as follows:
Why is the intensity of the high angle diffraction peaks so much greater in the pattern measured at 100 K than in that measured at 300 K?
A very similar pattern can be seen here: http://www.intechopen.com/source/html/18055/media/image31.png
Just replace 67K by 100K.
Unfortunately for this question, I have absolutely no valid reasoning to give on how this works. So I would really really need help on this one.
Thanks for taking the time to read my question and I hope you can share with me some insight on how I can go on with answering the question!
