Abstract
PURPOSE:To retain a cathode and a heating element with a desired force by arranging the heating element on both sides of the cathode, a support member on both sides of this heating element, and a retaining force adjusting member. CONSTITUTION:A cathode 1, heating element 2, Wehnelt electrode 3, and two supports 5 which retain the cathode 1 and the heating element 2 are arranged and a concave 6 is provided on the outer surface of the support 5. A thread member 9 consisting of insulating materials is arranged between the support members 5. Spherical nuts 12 are screwed on the both ends of thread 10 and 11 and contact-engaged with the concave 6. By turning the thread member 9, an elastic member 7 is elastically deformed and both the cathode 1 and the heating element 2 are tightened or loosened.
