The electron quads are all set to negative polarity. The hadron Q1 and Q3 are set to positive polarity, but Q2 is set to negative polarity. For a first guess at current for electron dipole either scale from earlier run or use 909 A/T. Suggest that the electron dipole be set to 10-3 level and then quads scaled to match.
The trigger setup should be proton_1170-1700.settings .
For each carbon thickness run for 15 minutes. Have allowed 15 minutes for carbon door changes.
