| title: | A microwiggler free-electron laser at the Brookhaven Accelerator Test Facility |
| format: | conference procceeding |
| conference: | 11th International Free Electron Laser Conference |

| abstract: | The authors report the design and status of an FEL experiment at the Brookhaven National Laboratory Accelerator Test Facility. A 50 MeV high-brightness electron beam will be utilized for an oscillator experiment in the visible-wavelength region. The microwiggler to be used is a superferric planar undulator with a 0.88 cm period, 60 cm length and K=0.35. The optical cavity is a 368 cm long stable resonator with broadband dielectric coated mirrors. (8 References). |

| abstract: | The design and operation of a 50-MeV electron linear accelerator utilizing a low emittance ( gamma epsilon =5 to 10 mm-mrad) radio-frequency gun operating at an output energy of 5 MeV and a charge of 1 nC are described. Design calculations, early radio-frequency measurements, and operational experience with the electron gun utilizing a dummy cathode in place of the proposed photocathode emitter are given. The dynamics of the electron beam coming off the photocathode has been modeled with the programs PARMELA and MASK. General agreement as to the expected characteristics of the electron beam at the RF-gun exit has been obtained using the two programs. It was also verified that, with proper matching of the transverse beam, no increase of the transverse normalized emittance occurs at the linac due to the fundamental RF mode. (5 References). |

| abstract: | A partial study for a 6 GeV undulator based synchrotron radiation source for production of high brightness undulator radiation, in the angstrom region, is presented. The basic lattice adopted for the storage ring is a hybrid FODO Chasman-Green lattice, making use of gradient in the dipoles. The e beam current limits and the injection parameters are discussed.

| title: | A new method for pumping an optical klystron |
| format: | conference procceeding |
| conference: | International Workshop on Coherent and Collective Properties in the Interaction of Relativistic Electrons and Electromagnetic Radiation |
| year: | 1985 |

| abstract: | A novel method of operation for a transverse optical klystron (TOK) is proposed. The TOK is a device in which a relativistic electron beam produces tunable coherent radiation at short wavelengths by interacting with a powerful external laser and an undulator field. The authors show that, by selecting the external laser wavelength to be one of the harmonics in the undulator radiation spectrum, excellent output at short wavelengths can be realized with significantly reduced performance requirements for the undulator magnet and the storage ring providing the electron beam.

| abstract: | Describes the theory of the production of coherent XUV and soft X-rays using a transverse optical klystron (TOK). A TOK uses a high powered laser in conjunction with an undulator magnet to produce laser-like output of XUV radiation from the relativistic stored electron beam in the NSLS VUV electron storage ring.

| 5 authors: | | | | | |
| abstract: | An overview is presented of the special radiation sources development at the NSLS for incorporation in a 2.5 GeV X-ray storage ring and a 700 MeV VUV storage ring. This includes a superconducting high field multipole wiggler, lambda /sub c/=0.5 AA; a permanent magnet wiggler, lambda /sub c/=2.0 AA; a maximum photon energy undulator (5-7 keV); an undulator for a soft X-ray line or 'continuum' spectrum and a free electron laser source tunable in the 2500-4500 AA region. Source characteristics and status of development are given. In addition, the incorporation of a backscattered Compton photon source is being studied and relevant parameters are presented.

| abstract: | A free electron laser experiment is described, to be performed with the 700 MeV electron storage ring of the National Synchrotron Light Source. The experiment is designed to study the parameters of the fel in an electron storage ring and the performance of this laser as a source of short wavelength radiation in the VUV region of the spectrum. The initial experiment will be carried out at a wave length of approximately 3000 AA, utilizing a permanent magnet undulator. For an average electron current of 1 A distributed in three beam bunches, the small signal gain per pass (relative enhancement of the radiation intensity per electron bunch pass through the undulator) is calculated to be approximately 10%.
