In the evening of Saturday May 15, we have reached a new peak luminosity record of 6 1028 cm-2s-1 This is about twice the peak luminosity of the last week-end and has been obtained colliding 3 bunches of 2 1010 protons in ATLAS. It proves that LHC is steadily progressing as expected. Overnight ~3 nb-1 of integrated luminosity have been recorded (and more is just coming...) with the usual high efficiency of the ATLAS data acquisition system.
