The Clinton P. Anderson Meson Physics Facility (LAMPF) at Los Alamos National Laboratory (LANL) provides physicists with 800-MeV protons and secondary particles with which to do nuclear physics and other experiments. The secondary particles are generated by the interaction of the 800-kW proton beam with graphite targets in the experimental area. After leaving the experimental area, the main proton beam enters the Isotope Production Facility and the Radiation Effects Facility. The protons are now at energies of 500 to 600 MeV. At these energies, the protons still can penetrate approx. 190 mm of copper. Stopping the proton beam in a compact structure requires the use of water cooling to dissipate the beam's remaining 375 kW. The LAMPF beamstop was built using circular disks of plated copper that are water cooled. The disks are 190 mm is diameter, range in thickness from 7.5 to 140 mm, and are placed inside a stainless steel cylinder with external manifolds for water supply and return. Group MST-14, of LANL's Materials Science and Technology Division, operates a hot cell laboratory designed and built for the examination and handling of highly radioactive materials. The hot cell laboratory consists of two blocks of hot cells, each block having eight cells. We used one of these cells to disassemble the Meson Facility beamstop. The authors designed and built a remotely operated milling machine to disassemble the beamstop. The mill was designed specifically to disassemble the Meson Facility beamstop remotely in one of the hot cells.
