Magnetic Field From Feshbach Coils
See Dylan #2 pg. 84 for details of measurement.
See Feshbach Coil calculator for details of calculation.
*Probe was coarsely positioned at the center by finding the minimum field of the coils in anti-helmholtz configuration.
*The gradient at 4mm from the field center corresponds to the displacement of atoms in the lattice from the field center.
Results:
Calculated | Measured | @ 194A | |
Bz(z) | 1.11 G/A | 1.16 G/A | 225 G |
Bz'(4mm from center) | 1.32E-2 G/cm/A | 1.38E-2 G/cm/A | 2.68 G/cm |
Bz"(z) | 3.31E-2 G/cm2/A | 3.46E-2 G/cm2/A | 6.7 G/cm2 |
