FU105大功率广播发射管用碳化镧钼阴极研究

A Study on Carbonized La-Mo Cathode for FU105 Large Powerful Broadcast Emission Tube

摘要:

研究了FU105大功率广播发射管用碳化镧钼阴极，参照碳化钍钨阴极FU105管的制备工艺，实现了镧钼阴极的碳化以及镧钼阴极FU105管的排气和老炼。通过镧铝阴极FU105管的性能测试，对碳化镧钼阴极的发射能力和稳定性进行了分析。结果认为：FU105管碳化镧钼阴极的发射能力可以达到碳化钍钨阴极的水平，但其稳定性还有待改进。

Abstract:

Carbonized La-Mo cathode applied in FU105 large powerful broadcast emission tube has been studied. Referred to carbonized Th-W cathode , the carbonizing techniques of La-Mo cathode was worked out. Exhausting and seasoning of carbonized La-Mo cathode for FU105 tube were carried out. Through the performance test of FU105 tube equipped with La-Mo cathode, the emission capacity and stabilization of carbonized La-Mo cathode were analyzed. The results show that the emission capacity of carbonized La-Mo cathode for FU105 tube has reached that of Th-W cathode, but its emission stabilization is not very good.
