The tube is to be a sealed-off, selfcontained unit consisting of an electron source, the necessary electron optics for performing the required write and read functions, and a storage structure containing approximately 10 million elements. During this quarter the first fly's-eye lens-experimental tube structure was assembled and tested. This tube (ETS-2) was assembled with a phosphor screen in place of the target, and tests of the beam control elements were made. The tube performed to our expectations. Tube ETS-3 was assembled. Fly's-eye lenses were assembled and tested to determine their dimensional stability when subjected to a vacuum bake.
