This article introduces briefly the process of design and characteristic of structure of db930 tube and discusses the main problems of technology and technique which was met during the manufacture and the measures having been adopted are emphatically . it discusses the solve measures in following six aspects : the filament current is too large , carbon deposits during the carbonizing of cathode , the capacitance between the first grid and the second grid is too large , transpiring happens inside the tube , the insulation resistance between the electrodes is too lower when the filament is on and the ability of bearing high voltage is too lower 本文簡略地介紹了db930的設計過程及其結構特點,重點論述了在試制過程中遇到的主要工藝技術問題及解決問題的措施,圍繞解決燈絲電流大、陰極碳化時積碳、一柵和二柵之間的電容大、管內蒸散、熱態時極間絕緣低、耐高壓的能力差等六個方面的問題進行了論述。

The plasma boundary can be identified by filament current method with the magnetic signals from probes around the plasma 摘要根據等離子體邊界附近的磁場測量信號,利用電流絲模型快速識別了等離子體的邊界。
