Diffraction Day
03/08/08 15:16 Filed in: Work Experiments
Today was a day spent in reciprocal space. A day for diffraction.
I suppose that's not so uncommon around here, but it was still a day full of experiments. My time was divided between x-ray diffraction on a coworker's metal-oxide crystals and electron diffraction from the surface of my own samples. It's been a long day and I'll be glad to have a little rest. Tomorrow I'll come back to swap in my own sample to the x-ray beam for (hopefully) the last repeat of this particular process.
The data looks interesting, though it's not actually anything new.
These are low energy electron diffraction (LEED) patterns. I should explain what that means, but for now I'm just going to leave the pictures on their own. I should also explain what the dots themselves mean, but again... I'm tired and lazy at the moment.
The modifications I made to the diffractometer (xray detector device) seem to have worked. We took data both yesterday and today and everything seems to have held together. It's always a good feeling when some of your effort has the intended effect of improving the situation instead of breaking it further.
