keyword=polarity flip confirmationFirst of all, Ed Folts stopped by and confirmed that the
L-HRS is ready. The magnets are ramped up to P0 = 2.35.
Second, the tools GUI shows "P" for positive. See fig 1.
Third, this has been known to be false in the past, so we
checked the gaussmeters and dipole NMR :
Gaussmeter .... before flip ..... after flip (now)
Q1 .......... -0.15 ......... +0.15
Q2 .......... +0.53 ......... -0.53
Q3 .......... -0.47 ......... +0.47
NMR
D1 .......... 0.87 .......... 0.87 "positive"
Waiting for beam ...
