Entry number 129818

Septum acceptance blocked with lead bricks.

Run 3170   up to 38 uA.
Run 3171   ramping current. Lowered lumi HVs by about 50 V to allow
           higher current. Went to 68 uA.
Run 3172   at 69 uA.

Roughly, the temperature was measured from the stripcharts as:
                 Right            Left
Temperature   T1     T2   T4     T1    T2    T4
 baseline     6.4   5.75  6.1     (not recorded, septum ramping)
   38 uA      6.95  5.90  6.60  6.55  5.05  6.60
   69 uA      7.35  6.20  7.05  6.85  5.30  6.90
Strip charts will be logged separately.

******
Beam to 5 uA, raster to 1.6x1.6.  Starting position scan.

Run 3173...  4bX = 2.9 mm

          Right      Left
Temps    T1    T2   T4    T1     T2    T4
3 mm    6.95  5.9  6.6   6.65   5.1   6.7
6mm trips the left septum, both septum temps spike

Run 3175...  Right septum only, +5mm but we didn't stabilize, as we
decided this test wasn't worth anything with only one septum.

*******
moved to Al dummy target.
setting raster to 3.0mm x 3.2mm.  Beam position roughly zeroed on
bpms 4a and 4b.
Run 3176... Aluminum target, Right septum only, 38 uA.  Lumi3 HV adjusted at 
event 2000.

             Right    
Temps     T1    T2    T4 
Alum.    7.00  5.95  6.65

*******
moved to Carbon target.
Run 3177... ramping to 69 uA. Changing lumi HV.
Run 3178... 69 uA, Lumi HV stable. (3x3 raster, beam zeroed in bpms)

             Right    
Temps     T1    T2    T4 
Alum.    6.65  5.70  6.30

*******
moved to Lead target
Run 3179... low current, checking raster and lumi
Run 3180... 15 uA, raster about 2.1x2.1 mm.  Left septum still ramping.
Run 3181... 13 uA. Left Septum at current.  Lumi2 HV was bumped up
before this run to give good signal.

            Right
