The planned photon diagnostics beamlines at the Advanced Photon Source
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.
