A test facility developed at the Budker Institute is designed for experimental simulation of effects ITER-scale transient heat loads on plasma facing materials. Employing a long-pulse electron beam creation transients has advantages low direct pressures surface material and lesser limitation power density by vapor shielding. In addition, relative modest attendant background light allows using set diagnostics observation erosion dynamics. The includes fast imaging in near infrared, scattering...

Background: The rate \lambda_pp\mu\ characterizes the formation of pp\mu\ molecules in collisions muonic p\mu\ atoms with hydrogen. In measurements basic weak muon capture reaction on proton to determine pseudoscalar coupling g_P, occurs from both atomic and molecular states. Thus knowledge is required for a correct interpretation these experiments. Purpose: Recently MuCap experiment has measured \Lambda_S singlet atom, employing low density active target suppress (PRL 110, 12504 (2013))....
