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):

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.)

2.0T data

Media:Grad_2.0T.pdf gradients on the y-component of the field,By, for 2.0T. Top left: 2D map (By in blue/red/green, Bz in light blue and Bx in magenta), 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).

1.8T data

Media:Grad_1.8T.pdf 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).

Media:Grad_1.8T_zoom1.pdf Same as above but zoomed with -10cm<z<+45cm.

Media:Grad_1.8T_zoom2.pdf Same as above but zoomed with -10cm<z<+20cm and normalized gradients are in ppm.
