Back from the ECM-30 meeting in Basel

Back from the ECM-30 meeting in Basel

During this week, I was in Basel to participate in the 30th meeting of the European Crystallographic Association (ECM) – the first time for me to participate in this conference. There were way more people than I had expected – I heard mentioned around 920 participants – and the whole thing was super inspiring.

I had actually tried getting a talk about my almost-ready to publish work on staging in LSCO, but I only got to present a poster. I did, however, get to catch up with a few people, as well as meet some of the people that I met at the Aperiodic Crystals school back a few weeks ago in Antwerp.

Monday evening there was a Young Crystallographers Mixer at the Bar Rouge in the second-highest building in Basel. The view was amazing, the drinks were great, and the music was loud. Quite a fun experience, although I’m not sure whether it worked well for networking or not..

Tuesday evening I got to visit the new Dectris headquarters in Baden-Daettwil, with a really interesting tour, as well as some awesome barbecue to top it off afterwards. It was really cool to see where they make the Pilatus detectors that I’ve seen so many times, as well as hear about all of the newer products they have been developing, and the history of the company.

The venue itself was really great, and there was a professional team of conference arrangers that took care of the practicals – everything ran so smoothly! We also had some pretty long lunch breaks, so there was good opportunity to get around Basel a bit. I might actually go to Basel again on a vacation some day, it was a great city – and the public transport was very efficient.

Finally, the conference dinner on Wednesday evening was held in the Zoo in Basel, in one of the big restaurant halls. Before the actual dinner (which was awesome, by the way), we were divided into groups and sent on tours around the Zoo. I got on the tour in their little aquarium, where one of the biologists showed us around in the back, where they breed corals, seahorses, and jellyfish. It was super interesting, and way too short. I could have stayed there for hours and hours.

Another DMC beam time on LSCO+O, and a little PCMO

Another DMC beam time on LSCO+O, and a little PCMO

From November 21 to 28 we had another beam time at the DMC instrument at SINQ, where we measured reciprocal space maps for two of our LSCO+O crystals.

I arrived a couple of days early to align the samples, and had some very late nights because things didn’t want to work – as is seemingly the usual when aligning crystals… If nothing else, I got to entertain myself with how much the sample holders looked like little robots.

The measurements themselves went perfectly, and we had some extra time to put a powder sample of PCMO on the instrument in the end. Hurray for beautiful data to take home!

Yet another beam time, now with students!

Yet another beam time, now with students!

I just got home from Switzerland, once again, this time from a beamtime at the DMC powder diffractometer, where I was measuring on one of our LCO+O single crystal samples, in order to map out part of reciprocal space (both for the crystal aligned in the cb- and the ab-plane). It was some really cool measurements, and I think I’ve already found the front page image for my thesis!

I actually started out the trip with starting up a beam time at the RITA-II instrument, where a YMnO3 sample were to be investigated. That was also really exciting – and that experiment continued during my own DMC beam time as well (sadly I didn’t have time to follow it all the way though, but their results looked really cool!).

Some of the students from the neutron scattering course were down there with us, to follow the two experiments. That was really fun, but I hadn’t expected how hard it was to help them to understand everything, when I didn’t even understand half of it myself! Usually beam times are really tiring, but this really took the price!

The DMC data weren’t really the most perfect data to do structure refinement from (in the cb-plane we only got 12 structural peaks, and some of them were of really bad resolution), but we saw some cool temperature dependencies, and already have some new proposals out for TriCS and other instruments in order to explore those things more. We also got a friendly beam time of two days at the new EIGER instrument, which will be really cool to work with.

This trip also marked the end of the neutron course, although I still need to correct a few reports, and help a few more of the students with their final project. But all in all, it’s been fun teaching in the course, even though it has been quite hard at some times!

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.

Helium and nitrogen refill

Helium and nitrogen refill gives a lot of smoke

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.

A little weekend trip to Basel

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 – especially the Tinguely museum was interesting, with so many odd sculptures!

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.

PSI detwinning beamtime

PSI detwinning beamtime

Yesterday, I returned from a long week in Switzerland, where I’ve been on a beamtime at the RITA-II instrument at the SINQ neutron source at the Paul Scherrer Institute (PSI).

I was there along with Astrid T. Rømer and Linda Udby, doing measurements on three different LSCO crystals. We tried detwinning them using magnetic fields, but it ended up not working at all.. Week well spent! Well, at least I got some training in aligning single crystals, and we did get some beautiful data.

We’ll have to look at some different techniques for measuring detwinning than neutron scattering (possibly dilatometry), before we want to do anything with neutrons again.
