PMQ3 version 2
Magnetic Measurements
BL vs X fit
• BL vs X runs 1, 2 & 3
• Mean Integrated Gradient = 8.3467 +/- 0.0096 T
Temperature =
21.7 +/- 0.32 degree C
BL vs. X plots
Integrated Gradient measured by
hall probe
• BL along z vs X runs 4, 5 & 6 using hall
probe
• Average integrated gradient = 7.9357 +/0.04686 T.
• Ratio of the integrated gradient of wire to
the integrated gradient of the hall probe
measurements = 8.3467/ 7.9357 = 1.0518.
This ratio is a bit high, should investigate
more.
Old Data using 3458A
• Measured integrated gradient using Metrolab
instead of HP 3458A because there were too
few points for the 3458A measurement. The
deadtime of the 3458A measurement was
causing a significant under reporting of the
voltage for PMQ3 (~27%).
• BL vs X run 2, which uses the 3458A has a
Integrated Gradient = 6.7984 +/- 0.016398 T.
