My first beamtime at ESRF

We were lucky to get a few days of beamtime on the hard X-ray instrument ID11 on the ESRF in Grenoble, France: from December 1st to 3rd. We measured reflections for several of our LSCO crystals at different temperatures, to get some of the beautiful superstructures in even better resolution that before.

A little look at what the data taking looked like:

I also got to see the mountains surrounding Grenoble from a new direction – I’d never all the way down south by the synchrotron on campus, and had no idea that there was a little roundabout down there either. Either way though, the view was awesome on the days we had sunshine!

ADD2013 workshop at ILL

During the last week, I’ve been in France, participating in the ADD workshop at the ILL in Grenoble. It has been a week of tutorials and lectures on different programs and methods that are used for real-space analysis of diffraction data. I got to test out the PDFgui program, which was interesting – since I’d heard about it at the conference in Santa Fe last October.

I got to present a poster as well, but simply used the same poster as the one I presented at the Flipper workshop back in January. I still did not get much of a response in terms of ideas on how to refine my superstructures, but did get plenty of friendly – although slightly unoptimistic – encouragement to continue my work. Sigh.

I also got a bit of time in the evenings to go explore Grenoble, and I found myself getting on the cable cars to the Bastille on top of one of the mountains surrounding the city. The view from up there was spectacular!

When I was done exploring and wandering around, I took the cable car down – and basically got the whole thing to myself. That prompted me to record the descent, with the view of the city in the early sunset – so if you’re interested, have a look at the video below!

Flipper2013 workshop at ILL

Since Tuesday, I’ve been at the ILL, attending this years Flipper workshop on the use of polarized neutrons. I was primarily there to learn, since I still haven’t gone much into polarized neutrons, and I have never used them for any experiments.

It was a great workshop, and I learned a lot of new things. I’m still not sure how relevant the things I learned actually are for my PhD project, but at least I met a lot of interesting people. I also presented a poster on the work I’ve done so far on my LCO crystal system – but since we haven’t been able to refine the structure yet, it was mostly a presentation of our awesome data. A few people had a look at it, and openly said that it was going to take a while to get that solved.. so that’s not comforting at all.
