I am the secondary on-call expert for the High Level Trigger system, therefore I am backing up the primary expert at P5.
Everyone is so excited around here. We are waiting for the beams to reach P5. They will eventually circulate around the LHC ring and that will allow their alignment, etc. The monitor that shows the beam status from the LHC machine reads “Injection Probe Beam”.
It is a great feeling to be here, to make history, to contribute a little bit to the improvement of our knowledge, to the improvement of our own humanity.
