Abstract

A compact deuterium–deuterium neutron generator for prompt gamma neutron activation analysis was developed at Institute of Nuclear Physics and Chemistry. A neutron yield of 3.6 × 10⁸ s^–1 was achieved during of the bombardment of a titanium drive-in target by a 6.8 mA deuteron beam at 115 keV. The deuteron beam was generated by a permanent magnet microwave ion source. An 85 h long run with 1.2 × 10⁸ s^–1 average neutron yield was performed at 85 keV and 3.7 mA. The operating mode of the neutron generator reached 99.95%.

紧凑型氘-氘中子发生器的开发，用于快速伽马中子活化分析

摘要

核物理与化学研究所开发了一种紧凑的氘-氘中子发生器，用于迅速进行γ中子活化分析。在115 keV的条件下，用6.8 mA氘核束轰击钛驱入靶时，中子产量达到3.6×10 ⁸ s ^–1。氘核束是由永磁微波离子源产生的。在85 keV和3.7 mA的条件下，运行了85小时，平均中子产率为1.2×10 ⁸ s ^–1。中子发生器的工作模式达到99.95％。
