Just a further update on the status of weekend running; Everything has 
been smooth and mostly uneventful, the ongoing nursing of the solenoid 
turbo pump from Friday continued into Saturday, but this now looks to be 
stable once again.  Last night, there were some minor issues with the 
orbit tuning of the machine, then early this morning, following the 
example of our solenoid, a turbo pump in the north linac caused a short 
period without beam.

Production data taking continues today on the liquid helium target until 
tomorrow morning, when the machine switches to beam studies.  During 
this period, we intend to empty the target and take some further data 
overnight Monday.

We will resume our usual Run Coordination meetings at 8:45 in the 
counting room tomorrow.

Regards,

Stuart (Hall D Run Coordinator)
