Read Day 1 here – visiting LHCb (Large Hadron Collider beauty experiment), the CERN Axion Solar Telescope (CAST) searching for axions, LHCb Data Centre, and Scintillating Fibre Tracker
During the ‘long shutdown‘ CERN opened many of its site to be visited upon by thousands of visitors over a two day weekend on 14 and 15 of September 2019. I was one of those visitors, after having found out about the whole event in June on the morning that registrations opened.
ALICE (A Large Ion Collider Experiment) is a heavy-ion detector on the Large Hadron Collider (LHC) ring. It is designed to study the physics of strongly interacting matter at extreme energy densities, where a phase of matter called quark-gluon plasma forms.
The ALICE Experiment seek to answer some fundamental questions, such as:
- What happens to matter when it is heated to 100,000 times the temperature at the centre of the Sun?
- Why do protons and neutrons weigh 100 times more than the quarks they are made of?
- Can the quarks inside the protons and neutrons be freed?
Waiting for the tour was a process in itself – at least three hours spent standing in 25 to 27C sunny weather somewhere in a French village alongside many other people!
Visiting the Prévessin Site
Unfortunately, I was really tired after ALICE and briefly spent time at the CERN Prévessin site which is named after a nearby French village. I went to an exhibition tent set up which also covered the specifics of LHC. The amount of specifics covered – from the absolute minute right through to the 27 or so kilometre site was amazing.
