keyword=Helmholtz Coil Current-Voltage Calibration + New Data/Code Folder on Target Computer for Ay/e'DHe3 Target holding field Helmholtz coils current-control voltage relation has been calibrated last night. Because it's calibrated with target enclosure in place and oven at 230C, the coil resistance is 3% higher than last calibration (Summer 2008, coils in open space). The new parameters, which better describes coil resistance curve, is updated into target field control code (BtoV.vi).
A new folder (c:\AyeD\) on target computer is make to separate target
data/code of upcoming Ay and e'D experiments from previous ones. At this
moment, it's a copy of c:\d2n, except new BtoV.vi.
