Field Quality Working Group Meeting
3 May, 2005
Random errors and population spreads superimposed, and samples are different. 2 MO singled out…
Spreads about same in B4 and SM18
Different behavior with magnet order
Difference between two labs of same order as spread
Octupoles: larger hysteresis and smaller transfer functions (can’t be explained by calibration factors)
Tolerance ± 7.4 10-5
