Description
The LHC main magnet production is well beyond half way and today the end by
September 2006 is in view. Warm and cold test assures us that the LHC nominal
targets are well at hand, while final assessment for the ultimate performance needs
a further year of cold testing. The dipoles quench level, which is recovering toward
the extremely good performance of the beginning of the pre-series, after a certain
weakening in the productions of the 2nd and 3rd octants, will be discussed in view
of the commissioning parameters. The action taken at the manufacturers in order to
improve as much as possible production quality and robustness (see for example
recent electrical problems in the SSS) in this last period of production will be
reported. Repair vs. replacement strategies will be reviewed, on the base of the
decision on spares taken in 2004 and in view of realistic assumptions on human and
financial resources available in the concerned departments, in order to derive what
and when possible actions must be triggered to optimize interventions, during
commissioning and operation.
