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 upstream maps
1D maps, along z, were taken at 4 field values: 2.0T, 1.8T, 1.5T and 1.0T. The 3 components of the magnetic field were measured.

Inclination study
For the 1.8T y=0 and the 2.0T 2D maps, two Hall probes were set to measure the Bx and Bz component of the field in order to verify at what level the x and z translations of the probes during the mapping were flat. We show here the results of these measurements.
2.0T data
Bz component:
Media: Ps_2d_p4_2T.pdf gradients on the z-component of the field,Bz, for 2.0T. Top left: 2D map, top right: color plot of Bz (in Gauss) in function of x and z (cm). Bottom left plot: Bz gradient along x normalized to Bz. Bottom right plot: Bz gradient along z normalized to Bz.
Media: Ps_2d_p4_2T_zoom1.pdf same as above but zoomed for -10<z<45 cm. Normalized B gradients are now in %.
Media: Ps_2d_p4_2T_zoom2.pdf same as above but zoomed for -10<z<20 cm. Normalized B gradients are now in 0/000.
Bx component:

Media: Ps_2d_p5_2T_zoom1.pdf same as above but zoomed for -10<z<45 cm. Normalized B gradients are now in %.
Media: Ps_2d_p5_2T_zoom2.pdf same as above but zoomed for -10<z<20 cm. Normalized B gradients are now in 0/000.
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.
