Initial commissioning is the first stage of the overall strategy for the year.
The initial commissioning phase should evolve through:
It is a relatively complex phase with necessary interplay between the various teams to allow beam-based commissioning of systems such as tune and orbit feedbacks, transverse dampers, RF etc. under appropriate conditions at the various phases of the operational cycle. It is an iterative process - each phase is necessarily visited several times
The aims of this initial commissioning phase are as follows.
The initial commissioning phase is performed with low intensity, low number of bunches, and generally safe beam. The output of this phase is taken to be first collisions in Stable Beams with a small number of bunches.
