  2. Saturday 20th October • 11:20 lost fill 3201 to spurious opening extraction switch of RCS.A12B1 (as Friday) • 123 pb-1 in 10h18m • Access for MPE piquet – switch replacement • Y.Bastian (QPS) joins Vincent Froidbisefor the intervention on RCS.A12.B1 • 13:30 Access to PM25 finished. Closing LHC... • 14:00 Ready for injection • SPS working on beam quality leading into… • Main Power Supply problem in the Booster LHC status

  3. Saturday 20th October • 17:00 Injection • Some steering required • QC latched on injection oscillation. steering on both beams correcting the lines but what improved the situation was to increase the SPS scraping. could inject but from time to time the IQC was latching… • 19:30 Start ramp • Without high bandwidth ADT • 20:20 Stable beams Fill 3202 • Initial luminosity: 7.02e33 cm-2s-1 • ALICE ~5e30 cm-2s-1 - will tweak up next week LHC status

  4. Sunday 21st October • 08:03 OP dump of 3203 • 172 pb-1 in 11h44m • 08:55 Re-injecting for physics LHC status
