Modular Coil Metrology Data for Current Center Shift Calculation Romer Arm Measurements are taken at each turn. Bundle dimensions are averages of all turns: 4 turns for Base and Top 11 turns for Septum and Sides (A & B Coils, 10 for Cs) Lateral (dx) is calculated as the average of the four sets of measurements: A Sides A Septum B Sides B Septum Radial (dy) is calculated as the average of the four sets of measurements: A Base A Top B Base B Top Caution: All Romer Arm Data except A Sides is positive with respect to local x,y. Side A has surface normal in x direction so measurements must be negated before averaging.
