12.01pm

Beam 1 now passed Point 5, home of the CMS detector. 

 

11.59am

Beam 1 just moments ago was at point 3.

Beam 1 has passed point 3!

11.56am

The TDI (a beam absorber for injection) has been opened, allowing Beam 1 to begin its journey through the transfer line and into the LHC.

11.53am

Beam 1 (clockwise) is ready to inject into the LHC near Point 2, home of the ALICE experiment.

What’s a splash event? Collimators, which are shutters used to absorb particles that go off-axis, can be put in the path of the beam near the experiments. Doing this when beam is circulating essentially turns the LHC into a fixed-target experiment, showering the detectors with particles.

Beam went smoothly through the whole machine. It’s fantastic to see it going so well after 2 years and such a major overhaul of the LHC. I am delighted and so is everyone in the CERN Control Centre - as are, I’m sure, colleagues across the high-energy physics community.

And now they are getting ready for beam 1.
