- Some possible transverse coupled-bunch instabilities to be studied in detail:

- 13/04/11 at ~ 13:19 => Beam losses on B2 only and at ~ 1.2 TeV. Action after that: ?.

- 20/04/11 at ~ 22:54 => Beam oscillations seen on the ADT at ~ 620 GeV. HEADTAIL monitor seems to reveal an horizontal head-tail mode 2.
