We present the planned photon diagnostics beamlines at the Advanced Photon Source. The photon diagnostics beamlines of the storage ring include two bending magnet sources and a dedicated diagnostic undulator. The bending magnet lines will employ the conventional UV/visible imaging techniques (resolution {sigma}{congruent}10 {mu}m) and the x-ray pinhole camera (resolution {sigma}{congruent}15 {mu}m) for the measurement of the positron beam-size (design value: {sigma}{congruent}100 {mu}m). The opening angle of die undulator radiation will be around {sigma}{congruent}3 {mu}rad for its first hamionic (23.2--25.8 keV), and {sigma}{congruent}=1.7 {mu}rad for its third harmonic (70--72 keV), providing a good resolution for measuring the positron beam divergence size (design values: {sigma}{congruent}9 {mu}rad for 10% vertical coupling and 3 {mu}rad for 1% coupling). The undulator and its x-ray, optics are specifically optimized for full emittance measurement of the positron beam. A major developmental effort will be in the area of detecting very fast phenomena (nanosecond and sub-nanosecond) in particle dynamics.
