<br>
<p>Chao, Josh and I started to measure the targat field at 19:20. We finished
the measurment by 20:40.</p>
<p>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. </p>
<p>Data analysis is on going. Result will be posted later. </p>
<p>
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 </p>
<p>B_tran if the field in the direction perpendicular to the dE plane.
All values are in gauss.
