Introduction As only lattice correctors are concerned, we do not
consider MCDOs & MCSs (~3700 magnets) Reminder: we measure modules and not the final
correctors Only data stored in MTF (Oracle WMM table ) are
taken into account (no preliminary data from modules approval)
We concentrate mainly on the dispersion of the Transfer Functions for the SSS correctors

Conclusions - modulus The measured systematic of the modulus is
often out of the limits scaled at low current (but this is not a problem)
The measured sigma on the modulus is < 0.33 % for all correctors: this satisfies the specifications, with the exception of MCBMs, for which a of 0.02 % was specified
FQWG 3/5 2005, V. Remondino AT/MEL

34
Conclusions - Phase The phase is not a issue as it can be easily
corrected modifying the ‘keys’

35
Conclusions : Alignment During the construction, modules are aligned
with particular care. Measurements show that we are within tolerances.
At the beginning of the production, MQTs were out of specs. Now the situation is under control.

Conclusions: Harmonics Recently, we observed a jump in the trend of the low
harmonics (b1, b2, a1, a2 too high) in MOs. The coil manufacturing process has been modified in
order to solve this problem. Measurements on last modules show that harmonics are back to usual values.
Part of this ‘bad’ production has been rejected or is in stand-by. However, we decided to accept most of the modules after discussion with A. Lombardi.
