[en] Operation of a new irradiation facility at the beam stop (Target Station A-6) at the Clinton P. Anderson Los Alamos Meson Physics Facility(LAMPF)began in May 1985. The facility is now fully operational. A closed-loop water system, a closed-loop helium system, remote handling procedure for activated materials, experiment change-out procedures, and experiment control equipment are all in place. Experience dictated a change in irradiation capsules from a system that used metal seals to a system that is completely welded. The seals were found to be unreliable and difficult to replace by remote means. Several materials have been irradiated in the direct 760-MeV proton beam. Material property changes as well as a helium production in a variety of materials are being investigated. A special sample holder that ca accommodate transmission electron microscopy(TEM)specimens, isolate them from the cooling medium, maintain fixed temperature, and retain essentially a stress-free state has been developed. Remote handling retrieval of these specimens is being developed. Activation foil measurements are being made to determine the secondary particle flux and spectrum (charged particles and neutrons) that result from interaction of the direct proton beam with targets at the beam stop

[en] Full text: Mexico presents its Tokamak Experimental Facility design under the necessary effort to develop Science and Technology into the thermonuclear magnetic confinement fusion area. This Research and Development Project (R and D) was approved from the Mexican Education Ministry (SEP, spanish acronyms) in 2007 for its development design stage at Facultad de Ingenieria Mecanica y Electrica (FIME) into the Universidad Autonoma de Nuevo Leon (UANL). We have made this effort in order to unify and consolidate under our tokamak experimental configuration facility (in the northern Monterrey city) the Mexican Energy Fusion Program and to participate in the nearest future, in ITER development, like the Mexican Fusion Research Group. The present design shows the development of a Tokamak Experimental Facility oriented to generate, innovate, understand, and develop scientific and technological knowledge, also to form researchers in the fusion confinement field Mexico desires with this initial effort to participate in the International Thermonuclear Experimental Reactor (ITER). This R and D Project involves multidisciplinary physics and engineering areas, that coexists into a nuclear fusion reactor, science and technology works together to establish a natural symbiosis between theory and experiments. We decide to use hydrogen plasma in this tokamak experimental facility with the next main characteristics: major radius 41 cm (R), minor radius 18.5 cm (a), aspect ratio 2.2162 (A), safety factor 1.9552 (q), plasma current 277 kA (I_p), β = 0.0532, toroidal field 1.3 T (B_t), ionic temperature 280 eV (T_i), electronic temperature 516 eV (T_e), electronic plasma density 2 - 3 x 10¹³ cm^-3(n_e). The stronger application of different sciences and technologies into our Mexican Energy Fusion Program, and the design and construction of this magnetic confinement device should allow us to develop, innovate and make significantly research exploding this new energy source concept, the magnetic confinement plasma is very complex, with this facility we can establish at first place our own schedule, a program to study and understand the different phenomena and with this aim, Mexico can participate in an integrate and intense collaboration with another nations in a great Research and Development International effort, like ITER does: A new energy source on earth.
