X-rays

My first beamtime at ESRF

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!

Teaching at a neutron and X-ray scattering summer course

These last couple of days (that is, Monday through Wednesday), I’ve been one of the teachers of the Applications of X-ray and Neutron Scattering in Biology, Chemistry and Physics course held as a collaboration between the University of Copenhagen, the University of Lund, the University of Roskilde, and DTU. It’s a three week course, and this is the first time for the course to be held.

The idea was to teach fairly young university students the basics of both neutron and X-ray scattering, in order for them to be prepared for the great new times with the ESS and MaxLab IV.

These first three days, where I was teaching, consisted primarily of introductions, and Monday and Tuesday I was teaching in split-sessions. These sessions were a split-up of the students in biologists and physicists (or, in practice, people not usually using a lot of math, and people better at math). The physicists were taught something about proteins, while Kim Lefmann and I were teaching the others to do some basic math, and understand things like complex numbers, Fourier transformations, waves and simple scattering. All in all, I think it went okay. But I guess I would have liked to be better prepared (I only found out that I was going to be teaching at Sunday evening…).

On Wednesday, I helped three of the lecturers with exercises. The last two weeks I have been working on a simulation of a simple neutron reflectometer instrument, to be used this single day. I never got the multilayers working flawlessly, but I got the rest working okay, and offered to help the three others to do the actual teaching, using the live-simulation tools that we also used during the tutorials that I was helping in on i Italy in July. This ended up kind of a mess, but I hope that the students learned something anyway…
