15、tubulation shall not extend beyond periphery. 2. Applies to area between periphery of this section of tube and concentric circle of 5/16 radius. 3. No part of iris assembly shall extend beyond body surface. 4. Reservoir shall be glass, or approved equivalent. 5. Maximum projection of reservoir shall
16、 lie within a cylinder of 1.250 diameter with axis colinear with tube axis. 6. A force of 200 pounds shall be applied to the face of the tube within the area indicated by shading. Dimension M shall not be permanently changed by more than 0.001. Qualification inspection required. 7. Body faces shall
17、be cadmium plated 0.0003 minimum, or shall be made entirely of monel, bright nickel or equivalent. If nickel Is required, it is recommended that it be used only when other metals can not meet the performance requirements. 8. Solder fillets permissible on peripheral surface near exhaust tubulation an
18、d electrode terminal. Slots shall be free from solder. FIGURE 1. Outline drawing of electron type 1B24A.
