CERN’s the Large Hadron Collider is about to be restarted by end of March and to remind us of the complexity of the beast that the particle accelerator is it has released a video tour of ALICE shot by a drone.
ALICE is located southwest of the 27-kilometre ring of superconducting magnets 56 metres below ground and CERN describes it as an underground telescope that aims to see aimed at the first instant of the Big Bang. ALICE’s primary focus is on a phase of matter called quark-gluon plasma.
Scientists believe that quark-gluon plasma formed shortly after the Big Bang at the beginning of the universe and made of quarks and gluons – the former are the fundamental building blocks of matter and gluons are said to carry the strong binding force that binds the quarks into protons and neutrons.
As for the LHC itself, the team is currently testing the systems that deliver the beams to ensure that the accelerator runs as smoothly as possible. The team will be injecting particles into parts of the LHC this weekend, there will be no fully circulating beams until the planned startup at the end of this month, CERN revealed.
“We will do two tests,” says Ronaldus Suykerbuyk of the LHC operation team. “Beam 1 will pass through the ALICE detector up to point 3, where we will dump the beam on a collimator, and for Beam 2 we will go through the LHCb detector up to the beam dump at point 6.”
