Chao, Josh and I started to measure the targat field at 19:20. We finished the measurment by 20:40.
The target coil was ramp up to 2.5 T at 90 degrees rotation angel. 45 points covering 145<phi<225 on the can surface, (phi=0 is along the coil axis), have been measured.
Data analysis is on going. Result will be posted later.
We have also measured 4 points at the front face of the 3rd arm at the following location: 1 point at the dE plane upper scitilator center. B_tran = 18.3 1 point at the dE plane lower scitilator center. B_tran = 18.9 2 points at the 2 PMTs of the dE plane lower scitilator. B_tran_left = 18.9, B_tran_right=19.9
B_tran if the field in the direction perpendicular to the dE plane. All values are in gauss.
