| + | |
| − | 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

| + | |
| − | 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
| + | |

| + | |
| − | <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>
| + | |
| − | <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.

| + | |
| − | 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>
| + | |
| − | <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

| + | |
| − | <br>
