直角式钛球升华器(图1)的这种结构设计,能方便地装入有冷却室壁的真空容器内。不论泵体是立式或卧式均可随结构要求灵活放置。最好是升华器轴线与泵体同轴,吸气面接受的钛原子轴向分布均匀而抽气效果也最好。钛球为T_(A1)钛板冲压成上、下半球后,,对合成为一个空心球壳。壁厚3毫米。钨丝单旋绕成φ16毫米、螺距为3毫米8匝的灯丝。 This structure of the right-angle titanium ball sublimer (Figure 1) is designed to fit easily into a vacuum vessel with cooling chamber walls. Whether the pump is vertical or horizontal can be flexible with the structural requirements. Preferably, the axis of the sublimer is coaxial with the pump body. Titanium atoms in the suction side are evenly distributed and the suction effect is also best. Titanium ball T_ (A1) titanium stamping into the upper and lower hemisphere, the synthesis of a hollow spherical shell. Wall thickness of 3 mm. Tungsten single spiral around φ16 mm, pitch 3 mm 8 turns of the filament.
