90 m optics commissioning

This report will describe the Virgo+ upgrades and the commissioning work performed between the first (VSR1) and the second Virgo Science Run (VSR2).. Some first results of VSR2 will

Data was recorded by the ALFA and TOTEM collaborations over ∼ 10 hours in stable conditions at 90 m with roman pots very close to the beam, down to 4.6 σ for primary collimators and

Going well beyond 90 m required many matching itera- tions to respect the ratio constraint and required to accept some compromises : the continuity during the de-squeeze

On the other hand, muons have well-understood energy deposition mechanisms and, unaffected by non-uniformities in the absorbers, they give a direct sensitivity to the width of

Roman Pots have been installed 240 m left and right of IP1 to allow to measure the absolute luminosity and the total elastic cross section for ATLAS with ALFA (Absolute Luminosity

We have developed a special optics with a β ∗ of 1000 m for two interaction regions (IR1 and IR5) in the LHC, to produce very low divergence beams required for elastic
