Book excerpt: The proposal for a Ultraviolet Free-Electron Laser Facility UV-FEL grew from the realization that neither existing lasers or synchrotrons, nor the third generation synchrotron radiation sources now under construction address all of the needs of scientists interested in the ultraviolet region of the spectrum, particularly with respect to the combination of continuous wavelength selection, high peak power and short pulse duration. Several workshops have been held at BNL and elsewhere which explored applications and source requirements in the 5 to 30 eV range. A critical requirement determined was is for very high peak power and short wavelength, especially for applications in chemical physics and non-linear optics. The need for wavelength tuning with the ease and agility to which synchrotron radiation users have become accustomed has also been strongly emphasized. With these initial parameters in mind, the accelerator physics staff set about devising ways to produce this radiation. Their design is for an FEL that has unique characteristics both in terms of possible applications, and in the range of radiation it could produce. In addition, the proposed location of the UV-FEL adjacent to the NSLS means that pump-probe experiments involving radiation from both sources will be possible. Each successive design has been reviewed in consultation with potential users in an iterative process to arrive at the present proposal design.

Available in PDF, EPUB and Kindle. Book excerpt: Brookhaven National Laboratory is designing an ultraviolet free- electron laser (UV-FEL) user facility that will provide pico-second and sub-picosecond pulses of coherent ultraviolet radiation for wavelengths from 300 to 75 nm. Pulse width will be variable from abut 7 ps to (almost equal to) 200 fs, with repetition rates as high as 104 Hz, single pulse energies> 1 mJ and hence peak pulse power>200 MW and average beam power> 10 W. The facility will be capable of pump-probe'' experiments utilizing the FEL radiation with: (1) synchronized auxiliary lasers, (2) a second, independently tunable FEL beam, or (3) broad-spectrum, high-intensity x-rays from the adjacent National Synchrotron Light Source. The UV-FEL consists of a high repetition rate recirculating superconducting linear accelerator which feeds pulses of electrons to two magnetic wigglers. Within these two devices, photons from tunable conventional'' laser would be frequency multiplied and amplified. By synchronously tuning the seed laser and modulating the energy of the electron beam, tuning of as much as 60% in wavelength is possible between alternating pulses supplied to different experimental stations, with Fourier transform limited resolution. Thus, up to four independent experiments may operate at one time, each with independent control of the wavelength and pulse duration. The UV-FEL will make possible new avenues of inquiry in time studies of diverse field including chemical, surface, and solid state physics, biology and materials science. The experimental area is scheduled to include a station dedicated to biological research. The complement of experimental and support facilities required by the biology station will be determined by the interests of the user community. 7 refs., 5 figs.

Available in PDF, EPUB and Kindle. Book excerpt: This document, the Preliminary Design Report (PDR) for the Brookhaven Ultraviolet Free Electron Laser (UV FEL) facility, describes all the elements of a facility proposed to meet the needs of a research community which requires ultraviolet sources not currently available as laboratory based lasers. Further, for these experiments, the requisite properties are not extant in either the existing second or upcoming third generation synchrotron light sources. This document is the result of our effort at BNL to identify potential users, determine the requirements of their experiments, and to design a facility which can not only satisfy the existing need, but have adequate flexibility for possible future extensions as need dictates and as evolving technology allows. The PDR is comprised of three volumes. In this, the first volume, background for the development of the proposal is given, including descriptions of the UV FEL facility, and representative examples of the science it was designed to perform. Discussion of the limitations and potential directions for growth are also included. A detailed description of the facility design is then provided, which addresses the accelerator, optical, and experimental systems. Information regarding the conventional construction for the facility is contained in an addendum to volume one (IA).

Book excerpt: Free-Electron Losers (FEL) are considered by many to be the fourth generation synchrotron light sources. The National Synchrotron Light Source (NSLS) at BNL is carrying out an extensive R & D program on short wavelength FEL leading towards a proposal for a VUV FEL User Facility. Research and development towards this goal are carried out at the Accelerator Test Facility (ATF). The ATF is a linac-laser complex capable of producing high brightness electron beams and high power loser pulses synchronized with the electrons. The ATF is the test bed for developing and testing the components needed for a successful UV-FEL At the some time the ATF is serving an advanced accelerator R & D program such as loser acceleration of electron beams and the interaction of intense laser pulses with high brightness electron beams.

Book excerpt: Brookhaven National Laboratory has developed a design for an ultra-violet free electron laser facility utilizing a seeded amplifier approach. Since the accelerator is a single pass device, resonator and outcoupler mirrors which are a difficult aspect of oscillator FEL designs are not required. The result is a source of high peak power VUV radiation with the mode structure, bandwidth and frequency stability of the input seed laser. The accelerator provides pulses of radiation at up to 10 kHz, so to maximize the utilization of the source, novel optical systems to share the radiation had to be developed. These include specialized alignment, beam transport, order sorting, and multiplexing optics. In addition, FEL on FEL pump-probe experiments are made possible by a variable optical delay of up to 10 ns operating in the wavelength range of 200 to 75 nm. Some aspects of the FEL design are also described to clarify the constraints and choices for the optical system.
