Description
Summary:The status of RF R&D activities in production and characterization of TGP-56FW beryllium grade is presented. The results of metallographic studies of microstructure and cracks morphology are reported for full-scale Be tiles (56×56×10mm) subjected to VDE simulation tests in TSEFEY-M testing facility (VDE-10MJ/m2 during 0.1s, 1 shot) and following low cycle thermal fatigue tests (500 thermal cycles at 1.5MW/m2). First results of plasma disruption tests (E=1.2–5MJ/m2, 5ms), which were obtained during the realization of Thermal Shock/VDE Qualification program of RF beryllium in JUDITH-1 facility, are also discussed.
