    New Crew on shift: Eric Voutier, Rikki Roche/Dave Meekins, Olivier Gayou
    ***************

    16:00 MCC is tuning the beam to improve the beam energy spread

    16:35 Beam is now tuned with OTR width less than 200um at 25uA; we are checking
    the beam spot size with an HARP scan.

    16:40 Hall A/B/C are not satisfied by the beam optics; MCC call the optics crew to
    adjust the beam tune; we'll be hopefully back in 2 hours.

    17:50 Beam is back, proceeding through the control of the beam spot and of the
    raster size (entry # 35711).

    19:00 Ready to start data taking for kin#6 at 100uA with energy lock on Hall A.

    21:45 The rate estimate for Kin#6 leads to 10 h (9.7M) data taking (entry # 35721).

    23:00 Go to dummy and carbon targets before the end of the present shift to study
    systematics; the next run will work on the increase of the statistics of Kin#6.
