| abstract: | The four Saturnus dipole magnets were calibrated with a Hall probe using a machinist's rotary table and a stepping motor to vary position. The setup was controlled by a Macintosh LC computer using LabView software. The field vs. current relationship was also measured. Single particle motion through the magnet was simulated, making a comparison of the real magnet to an ideal one. |

| abstract: | A 10.6 mu m free electron laser (FEL) operating in the high gain regime is under construction at UCLA. FEL physics significant to future short wavelength operation is emphasized including optical guiding, superradiance, saturation and self-amplified spontaneous emission (SASE). A 5 MeV RF photocathode gun illuminated by a UV laser supplies a high brightness electron beam which is injected into a plane wave transformer (PWT) linac for acceleration to 20 MeV. Recent measurements of the gun emittance as well as quantum efficiency are presented. The undulator is of a modified hybrid design producing approximately 7.5 kG peak field on axis with 5 mm gap spacing and 1.5 cm pole period. Simulation results which include three-dimensional effects are furnished. The present status and future plans of the project are summarized. (16 References). |
