PMQ3
Magnetic Measurements
BL vs X fit
• BL vs X fit
• y = 4.5903 x + 1.3418e-3
• Integrated Gradient =
4.5903 +/- 0.014207 T
Temperature = 23.4 +/0.3 degree C
Tooling Balls added
• Two tooling balls were added to PMQ3.
• The intergraded gradient changed with the
addition.
• Integrated Gradient = 4.772184 +/0.043384727 T
• Temperature = 21.2 +/- 0.2 degree C
Tooling ball check
• It seemed strange that 2 of the magnets
(PMQ1 and PMQ3) would change with the
addition of tooling balls and one (PMQ2)
would not. To test if adding tooling balls
did change the integrated gradient 2 more
tooling balls were adding to PMQ3. The
integrated gradient went down with the
second addition. See graph next page.
