    keyword=replaced enterance window assembly

    Replaced enterance window assembly. On inspection we could see deformation of the Be window that appeared to be caused by heat. Pictures of the window appear to show a hot spot in the center of the square raster. The pix are not great quality but can be found on the Hall A tech page.

    We were not able to see a hole in the wondow and a leak check was not done due to radiation, and possible be contamination. however when the new assembly was pumped down and leak checked,the vacuum problem was resolved.
