Abstract :
THE use of nickel and certain nickel alloys for the production of cathode-ray tubes is proving an important factor in the practical development of television. The cathode-ray tube, which translates electrical impulses into visual patterns, is an essential element of modern television sets. Within the tube, electrons emanating from heated metal are formed into a beam and projected on a fluorescent screen at the wide end of the tube. The screen is illuminated at the point of impact, and the beam, swinging across it at tremendous speed, creates the television image.
