Beam size measurement of the stored electron beam at the APS storage ring using zone plate optics and undulator radiation
- Advanced Photon Source, Argonne National Laboratory, Argonne, Illinois60439 (United States)
Beam sizes of the stored electron beam at the Advanced Photon Source storage ring were measured using zone-plate optics and undulator radiation. A gold Fresnel zone plate (3.5 {mu}m thick) located 33.9 meters from the x-ray source focused radiation of 18 keV, selected by a cryogenically cooled Si(111) crystal in horizontal deflection, and formed a source image in a transverse plane 2.41 m downstream. The sizes of the source image were determined from measured intensity profiles of x-ray fluorescence from a smooth nickel edge (1.5 {mu}m thick), fabricated using a lithographic technique, while the nickel edge was scanned across over the beam in the transverse plane. The measured vertical and horizontal sizes of the electron beam were 60{plus_minus}4.3{mu}m and 300{plus_minus}13{mu}m, respectively, in reasonable agreement with the expected values. {copyright} {ital 1997 American Institute of Physics.}
