AB  - We report on a system (ps-BPM) that can measure the electron source position and angular motion at a single location in a synchrotron bend magnet beamline using a combination of a monochromator and an absorber with a K-edge to which the monochromator was tuned in energy. The vertical distribution of the beam was visualized with an imaging detector where horizontally one part of the beam was with the absorber and the other part with no absorber. The small range of angles from the source onto the monochromator crystals creates an energy range that allows part of the beam to be below the K-edge and the other part above. Measurement of the beam vertical location without the absorber and edge vertical location with the absorber gives the source position and angle. Measurements were made to investigate the possibility of using the ps-BPM to correct experimental imaging data. We have introduced periodic electron beam motion using a correction coil in the storage ring lattice. The measured and predicted motions compared well for two different frequencies. We then show that measurement of the beam width and edge width gives information about the vertical electron source size and angular distribution.
