1. 20/09/2006 EM MSC September 2006

2. 20/09/2006 EM MSC “activities” (from the web page, by Giovanni) are: - Inertial damping - Local control - Tide control - Locking re-allocation to marionette - F7 control - Vertical control

3. 20/09/2006 EM The “objects” that allow these activities are: - SA-Suspension mechanics (ground-F7) - LastStage-Suspension Mechanics (F7-Mirror) - STD digital control electronics - STD analogic crate (actuation driving) - STD SA-suspension sensors/actuators - F7-ground sensors/actuators - STD local control sensors/actuators - STD interface with GC -SW to deal with all the systems above…. Maintenance and performance (credits,awards,prizes) of each item used by MSC concern object developer.

4. 20/09/2006 EM - MSC was created when Virgo commissioning was organized - Any update will take into account Giovanni’s recommendations and the actual developments of Virgo commissioning. - MSC is the direct product of the work done by each responsible of any object or activity. Virgo sensitivity (at LF !)Virgo duty-cycle My role is of secondary relevance. Namely, it is meant to allow all the people involved to efficiently contribute to the achievement of two main tasks

5. 20/09/2006 EM Tentative scheme of activity for the winter Note: software, modeling and simulation underlying

6. 20/09/2006 EM Environmental disturbance rejection Strategy improvements Extended “tidal” control Local environmental monitoring Interface with ITF Projection on B1_Acp Relation with LC/AA set-up Completion of further implementations needed Lock force re-allocation (BS) F7 damping from ground Vertical damping (Operation SW interfaces) Noise budget Mechanical TF Readout noise Actuation noise Digital noise

7. 20/09/2006 EM Noise budget: Dominique (driver) Alberto, Diego, Vincenzo… Interface with ITF: Dominique (driver), Ettore, Paolo… Ext: Gabriele, V.Granata… Environmental dist.: Paolo (driver) Ettore …, all people concern.. Further implementation needed: Alberto,Roberto,Vincenzo…El&SW Ext: Giovanni (re-allocation) Target: to bring MSC noise budget projection into MSC Target:duty cycleTarget:sensitivity (and operation) A collaborative effort

8. 20/09/2006 EM MSC will be accessible through the working area and each person involved in MSC activity will use it to publish useful information. All my best not to overlap or confuse information/responsibilities between “Suspension” and MSC. A major effort has to be done to “approach” the wonderful results achieved by Optics people!!!!

9. 20/09/2006 EM Shifts !!! Week Monday September 25 (no beam available) n -INTERFACE with other workgroups >DAQ load : probe channel reduction 1?2? -MSC (further needed implementations) >Extended “tidal ctrl”: PR(serial link, d.o.f reconstruction) WI,NI (serial link, GC algo change postponed) 1 -MSC (further needed implementations) >F7 ty-damp: WI,NI,BS,PR (HW, signal check, DSP card at least) 2

10. 20/09/2006 EM Shifts !!! Week Monday October 1 (according to commissioning schedule) n -MSC (further needed implementations) >lock force re-allocation implementation (BS) 1 -MSC (further needed implementations) >Extended “tidal ctrl”: measurements, test, implementation) 2 -MSC (further needed implementations) >vertical: meas. campaign to learn more about control specs? 1

11. 20/09/2006 EM In parallel -MSC (noise budget and ITF interface) >study and development of tools to project overall MSC noise budget on Virgo sensitivity INTERFACE with other workgroups >OPERATION : Check of implementation of already-existing SW interfaces
