Data


2D maps

2D (z,x) maps were taken at nominal field (1.8T) for 3 vertical (y) positions (0, +/1 cm), and at 2.0Y for y=0):

1.8T, y=0 2D results: Media: Ps_2d_y0_1.8T.pdf‎ Hall probes 1 (red), 3 (blue) and 5 (magenta) measured By. Probe 2 (green) measured Bx, probe 4 (light blue) measured Bz.

1.8T, y=+1cm 2D results: Media: Ps_2d_yp1_1.8T.pdf‎. All Hall probes measured By.

1.8T, y=-1cm 2D results:Media: Ps_2d_ym1_1.8T.pdf‎. All Hall probes measured By.

2.0T, y=0 2D results: Media: Ps_2d_y0_2.0T.pdf‎ Hall probes 1 (red), 2 (green), and 3 (blue) measured By. Probe and 5 (magenta) measured Bx, probe 4 (light blue) measured Bz.


1D maps

1D maps, along z, were taken at 3 field values: 2.0T, 1.5T and 1.0T for 3 transverse (x) positions, at at x=0 only for 1.8T.

Gradient study

We looked at gradients dB/B, mostly to determine where an NMR monitoring probe could be installed. (These probes do not tolerate gradient greater than 200 to 600 ppm.)

gradients on the y-component of the field,By, for 1.8T. Top left: 2D map (By in purple/red/blue, Bz in light blue and Bx in green), top right: color plot of By (in mTesla) in function of x and z (cm). Bottom left plot: By gradient along x normalized to By (in 0/00). Bottom right plot: By gradient along z normalized to By (in 0/00).

Same as above but zoomed with -10cm<z<+20cm and normalized gradients are in ppm.
