我们制成的φ150mm环形氚钛靶,成功地进行了试机,中子产额初步达到10~(11)n/sec,试机15分钟下降3％。氚钛靶的环宽为36mm,钛层厚度为1mg/cm~2,吸氚量为50Ci。 为了提高我所自制2000伏中子发生器的中子产额,决定试制大面积环形氚靶,以增大靶的有效面积,改善靶片冷却,提高中子产额。由于受当时吸氚设备条件的限制,能够吸氚的衬底尺寸,对角线长度不得超过50mm。所以决
We made φ150mm toroidal tritium titanium target, successfully conducted a test machine, the initial neutron yield reached 10 ~ (11) n / sec, test machine 15 minutes down 3%. Tritium-titanium target ring width of 36mm, titanium layer thickness of 1mg / cm ~ 2, tritium absorption was 50Ci. In order to increase the neutron yield of a homemade 2000 volt neutron generator, we decided to try out a large area toroidal tritium target to increase the effective area of the target, to improve the target cooling and to increase the neutron yield. Due to the conditions of suction tritium equipment at that time, the size of the substrate capable of absorbing tritium should not exceed 50 mm in diagonal length. So yes
