Use of VUV Imaging to Evaluate COTR and Beam-Steering Effects in a SASE FEL at 130 nm / Lumpkin, Alex H ; Chae, Yong Chul ; Dejus, Roger J ; Erdmann, Mark ; Lewellen, John W ; Li, Yuelin
We have continued to explore VUV operations on the Advanced Photon Source (APS) self-amplified spontaneous emission (SASE) free-electron laser (FEL). With the installation of a fifth VUV imaging station located after undulator 7 of an eight-undulator series, we have performed our most complete SASE gain curve measurements at 130 nm as well as obtaining beam profile, position, and divergence information. [...]

First Direct Comparisons of a COTRI Analytical Model to Data from a SASE FEL at 540, 265, and 157 nm / Lumpkin, Alex H ; Dejus, Roger J
We have been addressing fundamental aspects of the microbunching that is induced by the self-amplified spontaneous emission (SASE) free-electron laser (FEL) process using coherent optical transition radiation interferometry (COTRI) techniques. Over the last several years we have extended operations from the visible to the VUV regime at the Advanced Photon Source (APS) low-energy undulator test line (LEUTL) project. [...]

LCLS Undulator Design Development / Vasserman, Isaac ; Dejus, Roger J ; Den Hartog, P ; Moog, Elizabeth ; Sasaki, Shigemi ; Trakhtenberg, Emil ; White, Marion
The fractional variation in deflection parameter K between segments of the 130.4-m-long undulator line for the Linac Coherent Light Source (LCLS) must be < 1.5 x 10-4. Mechanical shims were used to set the undulator gap to control K in the prototype, but this is too tedious a procedure to be used for all 33 undulator segments. [...]

On the Issue of Phasing of Undulators at the Advanced Photon Source / Dejus, Roger J
Placing two collinear undulators in the 5.6-m-long straight sections at the Advanced Photon Source (APS) can answer the demand for increased brilliance. Whether longitudinal phasing needs to be taken into account for optimum spectral performance has been investigated. [...]

Generation of Short X-Ray Pulses Using Crab Cavities at the Advanced Photon Source / Harkay, Katherine C ; Borland, Michael ; Chae, Yong-Chul ; Decker, Glenn ; Dejus, Roger J ; Emery, Louis ; Guo, Weiming ; Horan, Douglas ; Kim, Kwang-Je ; Kustom, Robert et al.
There is growing interest within the user community to utilize the pulsed nature of synchrotron radiation from storage ring sources. Conventional third-generation light sources can provide pulses on the order of 100 ps but typically cannot provide pulses of about 1 ps that some users now require to advance their research programs. [...]
