## Introduction to Mantid and Python course

Late last night I landed in a plane from London, after a great week at the Rutherford Appleton Laboratories (RAL) in Oxfordshire, England. I’ve been following a week-long course on the instrument management and data analysis software Mantid, also including some rudimentary introductions to Python. A lot of it was very introductory (which was also the point, I guess), but at least now I have a good feel for how the software can be used both on an instrument and on my own machine for data analysis.

It’s a shame that there is no SXD instrument model in the software yet, so I could work on my time-of-flight data on there – but at least the guys teaching us (the same guys that made the software) were very eager to help people with starting up their own models too. So if I get the time, it seems like I have that option.

I stayed in the same small Bed & Breakfast in East Hendred as last time I was at ISIS (which is also at RAL), although this time I got a room a little outside of town, so I had to walk through their little yard to get to the bus stop. That made for wet shoes from the morning dew, but also some really pretty sunrises!

## A little detour to London on the way home

I spent a small part of Friday in London, before going all the way to Heathrow to catch my plane. I went out to the O2 Arena and then the Emirates Air Line. I took the trip back and forth over the water – with some absolutely beautiful views of the city! I also found time to go to Greenwich Park, where the GMT line is located – and I believe that it is a Unesco World Heritage spot too! The park is huge, but I managed to walk up the hill to the Royal Observatory to enjoy the view. You can basically see all of London from up there (that’s shown in the picture at the top of this post)!

## Working a couple of weeks at the Rutherford Appleton Laboratory

From April 1st to 13th, I’ve been at the Rutherford Appleton Laboratory (RAL) in Oxfordshire, England, to work together with the instrument responsible at the SXD instrument. We’ve been working on my data analysis, but the main thing we did was do extra measurements on two different laboratory X-ray diffractometers on small shavings of the same LSCO+O crystal that we had on SXD. These data will help me get an even better overview of my superstructures, since the X-ray instruments can measure for higher $$q$$ than what we’ve previously been able to.

The two diffractometers were at ISIS (an Oxford Instruments Gemini diffractometer) and the Harwell Research Complex (an Oxford Instruments SuperNova diffractometer), right on the RAL campus, so it was super convenient. We got so much new data – on several different small pieces of the crystal – and at least some of them have really nice resolution. I can definitely use this further!

I stayed at a cute lille Bed & Breakfast in East Hendred, a short ten minute bus drive from campus. The two cozy pubs provided some awesome meals for my dinners, and I felt super welcome there – I’ll be staying there every time I go to ISIS from now on. The guest house at campus is really, really not worth it compared to this place (it was basically the same price, for a way better room, and way better opportunities for dinner)!

## Beautiful London

On the first day, on my way to Oxfordshire, I took a little detour and spent a few hours in London. It’s the first time I’ve been in the city, and I spent my time walking around, mostly along the Thames – visiting the typical tourist spots like Elizabeth Tower, Trafalgar Square, the Tower Bridge, the Gherkin, and the Millenium Bridge at St. Paul’s Cathedral. I had a great time, and I’ll definitely return one day to have a look at some of the less visited places!

## A little side trip to Oxford

I spent one of my days working at the Bed & Breakfast in the morning, and then taking a short trip to Oxford in the afternoon. I visited some of the old colleges and had coffee and pecan pie at one of the (if not the) oldest coffee shops in Europe – Queen’s Lane Coffee House. I used one of those hop-on-hop-off tourist bus things, and they drove us around and explained how things used to work in the old days of the city. It was really interesting!

I stopped at the botanical gardens and had an ice cream while enjoying the beautiful Spring flowers. I also went to see the beautiful Renaissance dining hall at the Christ Church college, where they filmed the Harry Potter Hogwarts dining hall scenes: despite the long line and too many people, it was kind of fun to see.

## Weekend trip to bird-of-prey park and Stonehenge

On Sunday, April 7th, the local contact took me on a trip to a bird-of-prey park and Stonehenge, just to get out and do something, instead of sitting at the Bed & Breakfast working all weekend. It was super cool – and I’m really glad he suggested it!
