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_1700-4000.settings .

                The estimated data taking time is 180 hours. The estimated rate is 400-500 Hz.
