Field direction, Correction Coil, AFP Loss
Transverse +, OFF, 1.1%
Transverse -, OFF, 0.7%
Transverse -, S:+0.5A L:+0.5A, 1.4%
Transverse -, S:-0.5A 0.7%
Transverse -, S:-1.5A 0.7%
without correction coil, the optimal field direction (less AFP) matches
our expectation. However the performence of the corrections seem not
consistent with our calculation. Right now the Polarization is about
25%, will continue pumping and do more test later.
