After a brief reminder of the various requirements on the LHC, the strategy for a
staged commissioning with protons is summarised. Typical machine parameters and
associated performance levels are given for each stage. Dedicated runs with ions and
protons are mentioned, and how machine operation may be scheduled through a year is
shown.

In this report the issue of availability of electrical circuits, both for magnetic
elements and for RF devices, is considered. Based on the agreed stages to
commission and operate the LHC during the first two years, the minimum number of
required circuits will be presented and discussed. The analysis will also consider
how to deal with not required, but available circuits, as well as a...

Many beam measurements are essential already in the first phase of the LHC
commissioning. Others become necessary only as the intensity and the number of
bunches is raised. I will review the beam measurements needed in the various phases
of the LHC commissioning, their sequence, and the tools required for performing
them. An earlier talk at Chamonix XII discussed beam measurements on...

In order to counteract disturbances due to the decay and snapback of multipole
moments, misalignments, ground motion, and other dynamics effects, control of
the key beam parameters orbit, tune, chromaticity and energy will be an integral
part of LHC operation.
Manual correction of those parameters may soon reach its limit with respect to
required precision and expected time-scales....

The moment the first protons will be sent through LHC, the installation will become
subject to CERN’s radiation protection legislation. Proper pre-cautions will have to
be taken before the start-up of the machine and all significant radiation parameters
like prompt radiation and activation will have to be continuously monitored from
then on. Based on calculations, measurements and...
