| + | |
− | I have compared the measured points with the nominal beam line,
| + | |
− | assuming that the pole center (origin of mapping coordinates) is at
| + | |
− | the position X = -29.810 cm, Z =629.402 cm in room coordinates and
| + | |
− | using an angle of 6.5 degrees. The measured points are all within 5
| + | |
− | mm of the beam line, differing by about 2 mm at the pole root, and
| + | |
− | the slope of the line relative to the beam line is about 7 mr (0.4
| + | |
− | degrees).

− | 1.7 T, all scaled to 1.5 T) agree very well with each other and also

− | with Tosca, if the Tosca calculation is shifted by -4 mm (upstream).

| + | |
− | This configuration is nearly the mirror image (through Y=0) of
| + | |
− | Config. 1, and the field looks very similar to Config. 1, except
| + | |
− | that the variations between the probes (uncalibrated) are even
| + | |
− | larger, easily visible in the plots versus X. Most of this effect
| + | |
− | goes away when I apply the nominal calibration factors.<br>
| + | |
− | Here are some sample plots. All 3 excitations are very
| + | |
− | similar.

− | <h4>Comparison with Tosca, and alignment tests (added 24-Jan-2014)</h4>
| + | |
− | <ul>
| + | |
− | <li><strong>General agreement with Tosca calculations</strong> </li>
| + | |
− | The field shape vs <i>x</i> near the long exit edge is in good
| + | |
− | agreement with the Tosca calculations, from full field down to
| + | |
− | about 300 gauss

− | <ul>

| + | |
− | </ul>
| + | |
− | <br>
| + | |
− | I do not have actual power supply currents to compare with Tosca,
| + | |
− | but the ratios of field to power supply "PPM" values (using the
| + | |
− | prob calibration data at the center of the pole) are closely
| + | |
− | proportional to the Tosca B/NI ratios at 0.75, 1.5 and 1.7 T,
| + | |
− | which tells us that the saturation effects at high field are
| + | |
− | predicted correctly by Tosca. For B < 0.75 T, there is
| + | |
− | negligible saturation, and the ratio should be constant. The
| + | |
− | ratios at 0.05 and 0.1 T do not lie on the expected line, implying
| + | |
− | that there is a small (~2700 unit) offset in the "PPM" value.

| + | |
− | <li><strong>Alignment of Configuration 2</strong> </li>
| + | |
− | Matching the decrease of the field from maximum to ~1/2 max. with
| + | |
− | the Tosca calculation, the required offset in <i>x</i> is <br>
| + | |
− | 22.44 cm at y=0, <br>
| + | |
− | 22.48 cm at y=100cm, <br>
| + | |
− | 22.49 cm at y=200cm<br>
| + | |
− | as compared with the nominal offset of 22.40 cm. These offsets are
| + | |
− | the same for all 3 fields.<br>

− | <ul>
| + | |
− | <li><a href="Compare_15Tosca+map_xoffsets.pdf">1.5T field (at

− | and 22.44 cm</a> </li>
| + | |
− | </ul>
| + | |
− | <br>
| + | |
− | <li><strong>Alignment of Configuration 1</strong> </li>
| + | |
− | The x alignment is hard to test, since the field falls by only a
| + | |
− | fraction of a percent at the minimum and maximum x values of
| + | |
− | Configuration 1, but this small drop is not in good agreement with
| + | |
− | Configuration 2 (at high <i>x</i>) or Tosca (at high or low <i>x</i>).

− | A shift of the Configuration 1 <i>x</i>-coordinate by 0.7 cm
| + | |
− | gives much better agreement at both ends (see figure.) This
| + | |
− | effect is consistent at y=0, 100 and 200 cm, and at all 3 field
| + | |
− | values. <br>
| + | |
− | This shift is not important, because the field is essentially
| + | |
− | independent of <i>x</i> within Configuration 1 except for these
| + | |
− | end points. We can ignore the highest 3 <i>x-</i>values
| + | |
− | from Configuration 1, since we have the Configuration 2
| + | |
− | measurements for those points. (There are no electron trajectories
| + | |
− | in the region of the lowest <i>x</i> values.)<br>

− | The Y alignment of Configuration 1 is easy to compare with Tosca,

− | as there is a significant falloff at the last two values, 306.4
| + | |
− | and 308.9 cm. (The 308.9 cm setting is missing from the 1.5T map.)
| + | |
− | Agreement with Tosca requires shifting the Y value of the measured
| + | |
− | points by about +0.85 cm. Configuration 2 has no

− | <h4>Configuration 2 (mapped Jan. 14-15, 2014)</h4>
| + | |
− | This configuration consists of two files at each excitation: a
| + | |
− | rectangular region and an appended triangular region.<br>
| + | |
− | I have combined the two files onto a single grid, and plot the
| + | |
− | results below. <br>
| + | |
− | <br>
| + | |
− | At the highest X and Y values, the field drops to 0 because the
| + | |
− | measurements are made over a triangular region (see the "dotplots"
| + | |
− | to visualize this.)<br>
| + | |
− | <br>
| + | |
− | In the fringe field region, there is an interesting periodicity of
| + | |
− | about 70 cm, which may be due to the magnetic effects of some
