8am: Yet another early morning after a late night. I am getting too old for this (some would disagree with the “getting”). The shifters this morning are the same as those from yesterday morning, who were unfortunate in that there was no beam throughout their shift. They were more fortunate today as the beam was on. But our data acquisition system was not in such good shape. In the middle of the night the system had stopped working. A Windows-based laptop that controls part of the system seemed to have spontaneously rebooted itself!

8am: Another early start – meeting the two physicists and taxiing them to the beam area to be on shift for the next eight hours. Both are at the same institute – NCU Taiwan – but, as is often the case in our field, only one is from Taiwan – the other is from India.

9am: We reconvened at the test-beam area. First thing on the agenda was a second visit from the safety service, who wanted to see if we could improve on the grounding of our system – to protect people from any possible chance of electrocution. The risk was already extremely low (and, in any case, people are not permitted near the equipment when it is running) but we still managed to improve things a bit.

5am: I drove my wife and kids to Geneva airport. They are leaving for ten days in the sun, in the knowledge that even if they were not going away, they would see precious little of me for the next week: it is test-beam time at CERN!

More than half a year, a school trip to CERN, and a round of 13TeV collisions later, the week-long internship we completed at CMS over Easter is still the most awe-inspiring experience of our lives so far.

Born at the end of the ’70s, I was still in school when the heaviest of all quarks was discovered at the Tevatron: the top quark. Back then I had no idea what it was about. But reading an article in the newspaper I felt the excitement surrounding such a discovery. My interest for the smallest and most basic building blocks of the universe had been awakened. When I joined the CMS Collaboration in 2014, I had no doubt that the first measurement I would like to do was that of the production rates of top-quark pairs at the new energy regime of 13 TeV. Shortly after the restart of the LHC in summer this year, we began a journey where no-one has gone before.
