Another RITA-II beamtime

This was a hard couple of weeks! Just the day after getting home from the DanScatt meeting in Odense, I took a plane to Switzerland super-early in the morning, for a new round of beamtime at the RITA-II instrument at PSI.

With a little help from Christof Niedermayer, I used the first couple of days to get our sample aligned and get it on a new holder (it was already aligned in the ac-plane from the last beamtime, but we needed it in the ab-plane with a certain tilt out of the plane). Astrid showed up Sunday to help. Unfortunately, somewhere in the research phase we had found the wrong diameter of the magnet we were going to use, and it turned out that we had to start all over with a much smaller holder! That was a huge setback, and we had to start almost all over with the alignment. We weren't done yet when Linda showed up on Monday.

But we did get it working in the end, and did a lot of cool measurements on an incommensurate magnetic peak, and how it changed with applied magnetic field.

Astrid went home after the first week, leaving Linda and I to finalize the experiment (even though I guess this experiment was mostly for her project). Luckily, it was possible to script a large amount of the scans, and we actually took a whole day off to go to Basel Saturday June 9th. That was a really great little trip, and we saw a lot of fun museums and architecture.

Another fun thing that happened was that I met Ivana (who I met at the PSI summer school in 2011) in the instrument hall! She was at a beamtime at the SANS-I instrument, doing some measurements that I really didn't understand. But we had a little time to get some coffee at talk things over, that was nice.
