PMQ3
Magnetic Measurements
BL vs X fit
• BL vs X runs 3, 4 & 5
• Mean Integrated Gradient
= 8.1862 +/- 0.00624 T
Temperature =
21.7 +/- 0.32 degree C
BL vs. X plots
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.
