| los alamos national laboratory | <radiobiology> Major DOE research facility, located in Los Alamos, new Mexico, about an hour west of Santa Fe. Former home of a frozen-deuterium-fibre Z-pinch device, which was dismantled. Home to an active theory division, including the Numerical Tokamak Grand Challenge (being performed on the CM-5 massively-parallel supercomputer). Also home to former alternative-concepts experimental devices like Scyllac, FRX-A, FRX-B, FRX-C/LSM, ZT40, and the aborted CPRF which was killed in 1991 when it was almost complete (budget cuts). Currently there are some small in-house experiments, including one on electrostatic confinement as a possible fusion device, and/or a compact neutron source. They also do theory and experimental collaboration with other labs worldwide. (09 Oct 1997) |
