    1 Optics on Call Report/Schedule

    * 24 Jan-31 Jan: Edward/Alex (Outgoing)
          o Steady production run period; No calls
          o Periodically performed optics check; beta match, disp,
            coupling (from fOpt measurements) + path-length check,
            e-logged at BTlog
    * 31 Jan-7 Feb: Yuhong/Geoff (Oncoming)
          o Perform optics check; beta match, disp, coupling every time 
            fOpt measurement is taken + monitor path-length (e-log
            results at BTlog)
    * 07 Feb-14 Feb: Balsa/Todd
    * 14 Feb-21 Feb: Fanglei/Mike Spata
    * 21 Feb-28 Feb: Todd/Jay


    2 Hall B to 5th pass ~ Feb 1?

    * No, still 2nd pass
          o Hall B going to 5th pass by Feb. 15 (Hall C 3rd pass)


    3 Beam Studies Report 25 Jan 2012

    * C100 Test (Mike Spata)
          o Very successful test; both cryomodules brought to max.
            gradient, jitter studies performed, C100 subject to
            instability (along with C50 and C25 cryomodules in both NL
            and SL). Future work on ring buffer  to be done within the
            next 2-3 weeks and then Part IV for C100 test will be
            carried out.
    * Ray Trace (Ryan)
          o Baseline Ray Trace measurement with1S correctors executed.
            Purposely introduced mismatch (1R04 quad changed by 20%)
            served as a calibration for the Ray Trace data.

    5 M56 Inj. Optics

    * future inj. M56 optics tests - Yves
          o Review of test plan 'M56 inj. Optics - Part II' (Yves)
          o include Ray Trace measurement to characterize inj.Optics
            (Mike Tiefenback)
    * Inj Optics with G-Gaps modeled - Alex
          o New model of M56 optics including rigorous implementation of
            edge focusing of the chicane dipoles including specific
            H-Gaps for MBL and MBK dipoles. Significant asymmetry of the
            chicane quads (especially 0R02 and 0R06 - about 30 % asymmetry))


    5 Next week

    * Todd is back from travel
    * resume inj. M56 optics tests - Beam Studies Feb 8
    * Hall B to 5th pass ~ Feb 15
