ConclusionsConclusions
MCSMCS More than half of the total MCS needed have been produced. Average dX, dY close to zero, standard deviation ~ 0.05 mm Average dT ~ 0.2 mrad, standard deviation ~ 1 mrad Distribution of European MCS slightly narrower than
distribution of Indian MCS, but will probably end up the same
MCDOMCDO Insufficient data for European MCDO Unknown and not constant co-ordinate system for Indian
measurements mean we can’t check the distribution of all magnets.
For Indian MCDO checked at CERN, average dX, dY close to zero, standard deviation ~ 0.05 mm
Average dT ~ - 0.2 to -0.3 mrad, standard deviation ~ 1 mrad
