The Advanced Free-Electron Laser (AFEL) is being built at Los Alamos inside a large laboratory building. In addition to cost and available space considerations, several engineering issues affected the design of the AFEL and its facility. The 1300-MHz, 20-MeV electron linac required extensive radiation shielding and a short rf-waveguide run. Free-Electron Lasers (FEL) and photocathode-drive laser optics required a clean, constant temperature environment. New environmental, health, and safety (ES H) regulations placed constraints on the facility design and layout. In the past, many ES H regulations did not apply to pilot-scale experiments such as the AFEL; compliance is now mandatory. …

Description
The Advanced Free-Electron Laser (AFEL) is being built at Los Alamos inside a large laboratory building. In addition to cost and available space considerations, several engineering issues affected the design of the AFEL and its facility. The 1300-MHz, 20-MeV electron linac required extensive radiation shielding and a short rf-waveguide run. Free-Electron Lasers (FEL) and photocathode-drive laser optics required a clean, constant temperature environment. New environmental, health, and safety (ES H) regulations placed constraints on the facility design and layout. In the past, many ES H regulations did not apply to pilot-scale experiments such as the AFEL; compliance is now mandatory. The facility design included an earthquake restraint system for the radiation shielding, full compliance with the National Environmental Protection Act (NEPA), and minimization of airborne emissions. 8 refs., 4 figs.
