CATHODE STRUCTURE AND ELECTRON GUN FOR CATHODE RAY TUBES

摘要

The invention relates to a cathode structure intended to be inserted into an electron gun for a cathode-ray tube. The cathode comprises a cathode body (23) on the end of which is placed an emissive pellet (26), the cathode body being held in place inside a sheath (22) by supporting means which comprise: a first series of branches (31), each branch being connected on one side to the cathode body and on the other side to an intermediate piece (30); and a second series of branches (32), each branch (32) being connected on one side to the sheath (22) and on the other side to the same intermediate piece (30).
