The electron quads are all set to negative polarity.  The hadron quads are all set to positive polarity.   For a first guess at current for electron dipole either scale from earlier run or use 909 A/T.
 
 

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_1170_1700.settings .

               The data taking time is estimated to be 48 hours. The rates should be 860 Hz at 20 uA. Total number of triggers is 150M.
