The short story of Long Shutdown 1

Long Shutdown 1 (LS1) — the two-year period of maintenance, consolidation and upgrades to prepare the LHC and its particle detectors for collisions at an energy of 13 TeV — recently came to an end as the LHC was successfully restarted earlier this year. Although the term “shutdown” seems to imply a quiet period, this interpretation couldn’t be farther from the truth. Below we present in no particular order some highlights from what was a very productive two years at the CMS experimental site, as we take the final steps towards analysis data at the new energy frontier.

Night-shift live stream: #RestartLHC splash events

Yesterday, the LHC circulated the first beams in the accelerator after Long Shutdown 1 and CMS recorded some splash events.

This evening, we'll get a second batch of splash events and shifters are eagerly awaiting beam in the CMS Control Room.

We'll provide you with short updates from our shifters for the next few hours.

LHC data brought to life through music

Guest post by Chiara Mariotti


I first studied music at the Conservatorio di Torino when I was in high school but stopped during my university studies. I returned to music maybe 25 years later, when my kids started to play instruments (they play the trumpet and the saxophone). I felt great joy when I resumed playing and I discovered that I was still able to; my fingers were playing even without my conscious control of them. I soon joined the Thoiry harmony group (L'Echo du Reculet) and then enrolled at the local municipal school to take flute lessons again.
