  3. ATLAS • Fill 214 • At VAX SR: DP 1.5E-9 • In the right side of IP: VGI.188.1R1.X when in collision a pressure bump up to 1E-10 is recorded • At 18 m : 5.8 10-11 mbar / 9.8 10-11 mbar • At 22 m : 2 10-9mbar / 2 10-9 mbar

  4. ATLAS Extended • Some electron cloud is visible during the fill at 120 m from IP. • Q3L1/Q3R1 has electron cloud • At 58 m : 2.2 10-9 mbar / 1.9 10-9 mbar • At 120 m : 1.4 10-9 mbar / 1.3 10-9 mbar

  5. ATLAS history • Some signals with spikes at VAX during fills 2105, 2110,2117 2105 2110 2117 2124 2101

  6. CMS • Fill 214 • At VAX SR: DP 1.5E-9 • In all IP : pressure signal increases after collision to 5-8 10-10mbar • In the right side of IP, 18 m: VGI.183.1R1.X has pressure up to 1 10-8 mbar • At 14 m : 1.1 10-11 mbar / 1.1 10-11mbar • At 18 m : 6.4 10-10 mbar / 7.2 10-9 mbar • At 22 m : 2.3 10-10mbar / 2.8 10-10 mbar

  7. CMS Extended • Some electron cloud is visible during the fill at 120 m from IP. • Q3L5 shows signs of electron cloud • At 59 m : 7.5 10-10 mbar / 7.9 10-11 mbar • At 120 m : 1.7 10-9 mbar / 1.7 10-9 mbar

  9. LHCb • Fill 214 • At VAX SR: DP 1.8E-10 • Electron cloud at VELO • At VELO : 5.5 10-9mbar • At 19 m, right of IP : 1.1 10-10mbar • At 22 m : 2.5 10-10mbar / 2.8 10-10mbar

  10. LHCbExtented • Pressure between Q3R8 and D2R8 is dominated by TDI8R • No pressure spikes at D1L8 but some at D1R8 • At 70 m : 7.3 10-9 mbar / 5.4 10-9 mbar • At 100 m : 3.3 10-10 mbar / 4.2 10-9 mbar
