“…For this reason the codes are widely used in the design of future sources and the ongoing interest in their validation against the available experimental data and a cross comparison of their results are justified. The program MEDUSA has been extensively used in the prediction and the analysis of the LEUTL experiment [83,84]. In Ref.…”

The high brightness electron beam required by a short wavelength self-amplified spontaneous emission free-electron laser (FEL) may be reached only with an accurate design of the beam dynamics from the generation in the rf injector up to the undulator. The beam dynamics is affected by strong selfconsistent effects at injection, in the compression stage, and during the FEL process. The support of numerical simulations is extensively used in the predictions of the beam behavior in these nonlinear dynamical conditions. I present a review of available simulation techniques, currently exploited in the design of short wavelength free-electron lasers.

“…It is therefore important to characterize the statistical fluctuations of the experimental data collected at the optical diagnostic located after each undulator [10]. Figure 2 shows one of the most basic LEUTL SASE measurements for an operational wavelength of 530 nm; optical energy as a function of distance along the LEUTL undulator line.…”

Abstract. There is a strong desire for short wavelength (down to 1 Å), short pulsewidth (<100 fs), high-brightness, transverse, and longitudinally coherent light pulses for use by the synchrotron radiation community. Much effort is ongoing worldwide to advance this desire both experimentally, in theory and design, and politically. One of the ongoing experimental efforts is the low-energy undulator test line (LEUTL) at the Advanced Photon Source (APS) at Argonne National Laboratory (ANL). This experiment is based upon the self-amplified spontaneous emission (SASE) process, a method to attain a next-generation light source. This presentation gives an overview concerning the history and results of next-generation light sources, the results of the LEUTL SASE FEL, and the description of the upcoming first user experiment on LEUTL. We will also briefly review exotic schemes for future, next-generation light sources based upon FELs including biharmonic undulators and the possibility of interfacing of traditional x-ray lasers with FELs.

“…Parallel to these theoretical investigations, there have been measurements of 1) the nonlinear harmonic content in the joint Argonne National Laboratory (ANL) and Brookhaven National Laboratory (BNL) HighGain Harmonic Generation (HGHG) experiment at the Accelerator Test Facility (ATF) at BNL [16,17,23] and 2) the power of fundamental and second harmonic radiation, microbunching magnitude, and spectrum as a function of distance at the LEUTL APS SASE FEL [20,24,25,26,27]. Harmonic spectral measurements at the Institute of Scientific and Industrial Research in Osaka University, Japan [28,29] and nonlinear harmonic spectral, intensity, and CTR measurements at the VISA (Visible to Infrared SASE FEL) experiment at BNL [30] have also been made.…”

The mechanism of nonlinear harmonic generation in the exponential gain regime, which is driven by bunching at the fundamental wavelength, may provide a path toward both enhancing and extending the usefulness of an x-ray free-electron laser (FEL) facility. Related "exotic" generation schemes, which exploit properties of harmonic production in various undulator topologies, have been discussed both in the past and more recently. Using three different numerical simulation codes, we explore the possible utility of such schemes (e.g., harmonic "afterburners" and biharmonic undulators) at future light source facilities.
