At this time CAMD, a 1.3 GeV second generation storage ring, is the only synchrotron radiation facility in the Southeastern USA. To cater for the increasing demand for synchrotron light in this region a study is being made for a new high performance source. In keeping with its role as a regional source, it must be economical to construct and operate yet provide high brightness beams from its Insertion Devices. These will need to span both the soft X-ray region (1-2 keV) and the X-ray region up to at least 13 keV. A high brightness 3rd generation source is described which exhibits a beam emittance less than 10 nm rads at an energy of 2.5 GeV. By using a lattice cell derived from the Theoretical Minimum Emittance type, this performance is achieved in a circumference of only approximately 160 m. The economical, yet flexible, lattice uses vertically focusing gradient in the dipoles. The lattice functions and other parameters are presented of both a 12 cell double bend design and a 10 cell triple bend. The 12 cell gives a horizontal emittance of 8.5 nm rads and the 10 cell 4.6 nm rads. The dynamical stability of both lattices is described together with the beam performance from the anticipated insertion devices. The current status of the proposal is explained.

Throughout 2003 a sustained program of modifications and improvements has been applied to the CAMD light source. These affected the 7 Tesla wiggler, the RF system, the magnet power supplies, the control system, the diagnostics and the injector linac. These modifications and their impact on the storage ring performance are described, together with an analysis of where future improvements should be directed. The present performance and limitations of CAMD are described.

Beam based alignment is being applied to the CAMD light source. It is implemented by a flexible and versatile system of electronic shunts which are applied to each of the storage ring lattice quadrupoles. The essential design features of the electronic shunts are described as is the routine operation of the full system. The improvement to the corrected closed orbit from using the system is shown. Preliminary results are presented of the use of the shunts for correcting the lattice functions.
