  Diamond is the UK's new 3'rd Generation Synchrotron Light Source. The construction phase has just concluded and the first operation with external users is about to begin. This presentation will concentrate on the second phase of commissioning of the storage ring at the full energy of 3GeV, which began in September 2006, with a full set of 7 Phase I Insertion Devices installed. The current status and future plans will also be described.

  In Indus-2 there are 56 button type beam position monitors (BPMs), 48 horizontal and 40 vertical steering magnets. The measured orbit has been fitted by effective quadrupole misalignments by using SVD of the response matrix generated between BPMs and the quadrupole misalignments in the model obtained by setting the magnet strengths as per the current set in the magnets. We present the different global and local orbit correction algorithms developed for minimizing and controlling the orbit. The preliminary result for the orbit correction, at injection energy, in horizontal plane using best orbit correctors identified by doing SVD of the response matrix is presented. The results for the local four orbit bumps are also presented.
