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.

Beam energy ramping in Synchrotron Radiation Sources (SRS) requires synchronous increase in power supply currents attached to various magnets. This paper describes the implementation at various layers of control system architecture, experience of ramping beam energy from injection energy to 2 GeV. The total Ramping system hardware and software for both Magnet power supplies and RF cavity voltage are described with problems faced during the energy ramping. The implemented ramping system provides a tracking uncertainty less than 10μsec in time.
