The sealed neutron tube with drive-in target has good stability and long service lifetime. Alloying and overcoating a protective layer on target can effectively overcome the inherent defects of pure titanium target. The neutron yield of neutron tube hit by deuterium tritium mixed beam on pure titanium target was measured experimentally. The calculation value by SRIM is in good agreement with the existing experimental data, which verifies the reliability of the theoretical method. The neutron yields of neutron tube with scandium-titanium, molybdenum-titanium and niobium-titanium targets at different alloy ratios (0.2, 0.4, 0.6, 0.8, 1.0) were calculated. At the same time, the protective overcoating of alloy target was considered, and the neutron yield of the alloy target was calculated. The results show that the scandium-titanium alloy with 7.5 nm Pd overcoating and 0.4 doping ratio is an appropriate target film material for the neutron tube with drive-in target.

带输入靶的密封中子管具有良好的稳定性，使用寿命长。对靶上的保护层进行合金化和覆盖可以有效地克服纯钛靶的固有缺陷。实验测量了氘mixed混合束撞击纯钛靶材的中子管的中子产率。SRIM的计算值与现有的实验数据吻合良好，验证了理论方法的可靠性。计算了不同合金比（0.2、0.4、0.6、0.8、1.0）下具有scan钛，钼钛和铌钛靶的中子管的中子产率。同时，考虑了合金靶的保护涂层，并计算了合金靶的中子收率。结果表明，with钛合金具有7。
