|Ultimate bunch intensity||Bunch intensity corresponding to the expected maximum acceptable beam-beam tune shift with two operating experimental insertions. Assuming the nominal emittance (normalized emittance of 3.75μm) the ultimate bunch intensity corresponds to 1.7 × 1011 protons per bunch.|
|Ultimate powering||Hardware powering required to reach the ultimate beam energy of 7.54 TeV, corresponding to a dipole field of 9 T.|
|Upstream and downstream||Always related to the direction of one of the two beams. If no beam is specified Beam 1 is taken as the default. This implies that stating a position as being
’upstream’ without indicating any beam is equivalent to stating that the position is to the left.
