Field Mapping August 99:

First Week:

August 10 data: first runs. Phi runs for aligning the FieldMapper to the field.
August 11 data: Phi runs at the ends and center of the solenoid, and Z runs at phi=0 for aligning the FieldMapper beam to the magnetic axis and to (absolutely) align the probe cube to the field.
August 12 data: Diagnose sick Bz_bottom probe. Continue to align FieldMapper with phi-sweeps at the ends. Continue with angular alignment study of cube on carriage arm.
August 13 data: Start production FieldMapping with Sol = Forward and Toroid = Forward. New Z variable step option.

Second Week:

August 16 data: Continue production FieldMapping begun last Friday (Aug 13).
August 17 data: Complete production FieldMapping begun yesterday (Sol -, CF +).
August 18 data: Complete production FieldMapping begun on August 16 (Sol -, CF +). Take some field off data. Take some solenoid-only phi sweeps.
August 19 data: Take some field off data. Take some solenoid-only f sweeps. Take some field off data (especially phi sweeps). Take some CF-only z sweeps.
August 20 data: Take some data with R different from 13. Run with solenoid only.

Third Week:

August 23 data: Investigate strange behavior of Br probes when Solenoid was reversed on Aug 20. Also, test Gauss meters on different ranges.
August 24 data: Investigate Br probe behavior at R < 13. Leave CF off to keep things simple.
August 25 data: Investigate Br probe behavior at R = 13 by varying the shim under the hall-probe cube. Decide to run CF to keep muon shifters happy.
August 26 data: Complete Run Plan of Aug 25: Investigate Br probe behavior at R = 13 by varying the shim under the hall-probe cube. Decide to run CF to keep muon shifters happy.
August 27 data: Remove shim from cube and log data during step-wise charging and discharging of the solenoid.

Fourth Week:

August 30 data: Resume "production" fieldmapping: variable-step z-sweeps plus phi-sweeps at "ends of the cylinder".
August 31 data: Complete production FieldMapping series for CF Reverse, Solenoid Forward (begun on Aug 30). Add end-of-cylinder f sweeps.
September 1 data: Complete production FieldMapping series for CF Reverse, Solenoid Forward.

Fifth Week:

September 7 data: Proceed with configuration S/T = -/-. First clean rails and carriage bushings, adding fresh graphite to the latter. First checkout things with magnets off:.
