1 08h15: Injection.  Correction injection oscillations.  Transfer line steering.  Losses at 30% of dump threshold, limited by SPS scraping. 12h35: Start ramp. 13h15: Stable beams #2101. 16h39: Beam dump. Collected 30 pb -1  triggered by bad temperature reading on TT891A on DFBAJ_HCM, which caused the CS CM to be lost for a short while, which caused the PIC to fire Monday September 12 th 13-09-2011 LHC morning report

Collected 30 pb -1  triggered by bad temperature reading on TT891A on DFBAJ_HCM, which caused the CS CM to be lost for a short while, which caused the PIC to fire  BLM intervention: Deployment of the BLMLHC real-time server with changes on: - fix on the Study Capture buffer and - suppression of some of the debugging files. Several events for Capture, XPOC (beamDumped1 &2) and PM data have been sent to test the correct production of the data and their delivery. All tests completed successfully (including the sanity checks). 19h05: Injection. 20h11: Problem to load ramp for TCTVA.4R1.B2. 22h59: Fixed.
