The electron quads are all set to negative polarity. The hadron quads are set to positive polarity. For a first guess at current for electron dipole either scale from earlier run or use 909 A/T.  Set the quads by the READ BACK current not the set current.
 

Data taking
The T5 prescale should be one. The prescales for T1,T2,T3 and T4 should be set to give less than 2 Hz trigger rate for each. The T8 prescale should be set to maximum.

            The trigger setup should be proton_1700-4000.settings .

               Estimate that the data taking time should be 24 hours and the rates should be 1.5 to 2.0 kHz .
