| abstract: | The Brookhaven Accelerator Test Facility (ATF) will consist of a 50-100 MeV/c electron linac and a 100 GW CO/sub 2/ laser system. A high brightness RF-gun operating at 2856 MHz is to be used as the injector into the linac. The RF-gun contains a Nd:Yag-laser-driven photocathode capable of producing a stream of six ps electron pulses separated by 12.5 ns. The maximum charge in a micropulse will be one nano-Coulomb. The CO/sub 2/ laser pulse length will be a few picoseconds and will be synchronized with the electron pulse. The design electron beam parameters are given and possible initial experiments are discussed. (9 References). |

| abstract: | A theoretical study of the possibility of a free-electron laser in the XUV and soft X-ray region of the spectrum, using a counterpropagaing CO/sub 2/ laser beam as an undulator, is presented. A one-dimensional model is used to evaluate the single-pass power gain of such a device. The detrimental effects due to the energy speed, emittance of the electron beam, and the diffraction of the electromagnetic undulator are explicitly incorporated in the formalism. An oscillator experiment is also considered. The solutions of the optical pulse evolution equation in the weak field, low gain, and long-electron-pulse regimes are all derived. (27 References). |
