“…The APS has an FEL project known as the Low Energy Undulator Test Line (LEUTL) [17,18]. In order to push this FEL to saturation with fewer undulators and at shorter wavelengths, we embarked on a rapid program to build a bunch compressor for the APS linac [19].…”

elegant (ELEctron Generation ANd Tracking) is the principle accelerator simulation code used at the Advanced Photon Source (APS) for circular and one-pass machines. Capabilities include 6-D tracking using matrices up to third order, canonical integration, and numerical integration. Standard beamline elements are supported, as well as coherent synchrotron radiation, wakefields, rf elements, kickers, apertures, scattering, and more. In addition to tracking with and without errors, elegant performs optimization of tracked properties, as well as computation and optimization of Twiss parameters, radiation integrals, matrices, and floor coordinates. Orbit/trajectory, tune, and chromaticity correction are supported. elegant is fully compliant with the Self Describing Data Sets [1, 2] (SDDS) file protocol, and hence uses the SDDS Toolkit for pre-and postprocessing. This permits users to prepare scripts to run the code in a flexible and automated fashion. It is particularly well suited to multistage simulation and concurrent simulation on many workstations. Several examples of complex projects performed with elegant are given, including topup safety analysis of the APS and design of the APS bunch compressor.

“…The first LEUTL experiment examines SASE gain and saturation in three wavelength regions: the visible, ultraviolet, and vacuum ultraviolet [15][16][17]. This first LEUTL experiment is often referred to as the APS SASE FEL and utilizes a string of undulators that are similar to those found in the APS storage ring, each having an undulator parameter K of 3.1, a period of 3.3 cm, and a length of 2.4 m. LEUTL presently (Fall 2000) employs nine identical undulators spaced by ≅ 0.38 m. This space contains a combined function dipole-corrector and quadrupole magnet, electron beam diagnostics, and optical beam diagnostics [18].…”

Abstract. Wakefield effects due to internal vacuum chamber roughness may increase the electron beam energy spread and so have become an immediate concern for future x-ray free-electron laser (FEL) project developments such as the SLAC Linac Coherent Light Source (LCLS) and the DESY TESLA x-ray FEL. We describe a possible experiment to characterize the effects of surface roughness on an FEL driven by self-amplified spontaneous emission (SASE) operation. Although the specific system described is not completely identical to the above-proposed projects, much useful scaling information could be obtained and applied to shorter wavelength systems.

At the Advanced Photon Source (APS) at Argonne National Laboratory (ANL), a free-electron laser (FEL) based on the self-amplified spontaneous emission (SASE) process is nearing completion. Recently, an rf photoinjector gun system was made available to the APS by Brookhaven National Laboratory/Accelerator Test Facility (BNL/ATF). It will be used to provide the highbrightness, low-emittance, and low-energy spread electron beam required by the SASE FEL theory. A Nd:Glass laser system, capable of producing a maximum of 500 µJ of UV in a 1-10 ps pulse at up to a 10-Hz repetition rate, serves as the photoinjector's drive laser. Here, the design, commissioning, and integration of this gun with the APS will be discussed.
