neutron course

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!

Started teaching in the neutron scattering course

This week was the first week of block 1, and hence the first week of the neutron scattering course held at the Niels Bohr Institute. I was helping a bit last year as well, since I was hired to develop some different e-learning tools for the course, but this year I am an actual student instructor on the course.

We started Monday afternoon with some small introductions and a few exercises, and the small team (this year I think there are only about 12 students following the course…) is kind of cozy. Wednesday was the first long day, and since Kim went to Switzerland, Linda and I (and Peter Willendrup, who had promised to help with giving an introduction to McStas and the virtual machines we wanted to install on the student’s laptops, was also there) handled the day. Linda took care of lecturing about instrumentation, while I did a small MATLAB introduction and a little view of our local neutron source and He-3 detector tube. Most of the students seemed to get things running, and I think they’re ready for the startup of the real simulation projects in next week.
