The development of high-brilliance, hard x-ray synchrotron radiation
sources enables a broad range of basic and applied research. Maintaining
high performance in these sources is a primary goal, as is understanding
their limitations. The accelerator physics (AP) group at the Advance Photon
Source is involved in a number of areas of research that address
both the near-term requirements of users as well as the future development
of the APS in the longer-term. In this talk, I will focus on experimental
and analytic efforts to characterize the collective instability thresholds
and machine impedance in the storage ring. The goal for these
studies is overcoming the intensity limitations in a single bunch in the
near term. However, understanding the machine in more detail will enable
us to design and develop future capabilities with greater confidence.
In parallel, the AP group is also developing techniques to characterize
the storage ring lattice and develop new injectors. I will discuss these
briefly in the context of longer-term goals.
