Beryllium 7 Deposition

  • Preferential beryllium-7 deposition has been found in the higher temperature region of non-isothermal flowing lithium between 270/sup 0/C to 200/sup 0/C. Various methods for controlling /sup 7/Be distribution for application to the Fusion Materials Irradiation Test (FMIT) facility are examined ...
