:00 meetingEBH 4 Plans  Loss maps:  Asynchronous dump squeezed separated (1 ramp). Roman pots out.  Complete injection loss maps (betatron, positive and negative off momentum, asynch dump) (~2-3 hours).  If OK from MPP:  STABLE BEAMS Single_13b_8_8_8_pPb (1 hour of STABLE BEAMS)  Then: Injection of trains of p and Pb for the intermediate filling scheme: 200ns_96p_120Pb_4inj24bpi (2 hours of STABLE BEAMS)  No Roman pot insertion in STABLE BEAMS before Monday.

:00 meetingEBH 5 Pending  For the time being the gain of the damper is not gated as well as the BBQ reading  Extraction conditions and transfer line trajectory for ions to be checked  Margin for 1 cavity trip for RF HW interlock (1 hour during ramp down) could be re-introduced  Damper setting optimization
