The paper describes the preliminary studies regarding development of a new polymeric track detector known as poly (SDAC-co-ADC-co-APCC) for rapid detection of thermal neutrons induced alpha tracks. The polymeric detector with different percentages of natural boron (1–5%) content is prepared by cast copolymerization of Allyl Diglycol Carbonate (ADC) with Allyl Propargyl Carbonate Carborane (APCC) and 2,2′-Sulfonyl Diethanol bis (Allyl Carbonate) [SDAC]. APCC contains boron which increased thermal neutron sensitivity as boron has high cross-section for thermal neutrons. The etching conditions are optimized for this new polymeric detector and are 1 N NaOH at 60 °C for 30 minuets. It is noted that 3% boron containing poly (SDAC-co-ADC-co-APCC) detector is more sensitive than imported commercial (PADC)th and poly (APCC-co-ADC) detectors. It is observed that, in terms of number of net tracks developed, 3% boron containing poly (SDAC-co-ADC-co-APCC) detector is two and half times more efficient than (PADC)th and its signal to noise (S/N) ratio is almost two fold higher than that of (PADC)th ana poly (APCC-co-ADC). The optimized time for revelation of the tracks is 30 min [1 N NaOH at 60 °C] which is found to be one-fourth than that for (PADC)th and poly (APCC-co-ADC) [120 min in 6 N KOH at 70 °C].

聚(砜-碳酸酯-碳硼烷)共聚物,用于热中子诱导的α迹线的快速揭示

本文介绍了有关开发一种新型聚合物轨道探测器的初步研究,该探测器称为聚(SDAC- co- ADC- co- APCC),用于快速检测热中子诱发的α轨道。通过将碳酸烯丙二醇酯(ADC)与烯丙基丙炔基碳酸酯碳硼烷(APCC)和2,2'-磺酰基二乙醇双(烯丙基碳酸酯)浇铸共聚制备具有不同百分比天然硼(1-5%)含量的聚合物检测器[ SDAC]。APCC包含的硼增加了热中子的敏感性,因为硼具有较高的热中子横截面。蚀刻条件针对该新型聚合物检测器进行了优化,并且在60°C下1 N NaOH浸泡30分钟。注意,含3%硼的聚(SDAC- co -ADC- co-APCC)检测器是比进口商用(PADC)更敏感和聚(APCC--ADC)检测器。可以观察到,就形成的净磁道数而言,含3%硼的聚(SDAC- co -ADC- co- APCC)检测器的效率是(PADC)th和其信噪比(S / N)比是几乎2比(PADC)的倍高ANA聚(APCC--ADC)。为轨道的启示的优化时间为30分钟的1N NaOH在60℃下],其被发现是比用于(PADC)四分之一和聚(APCC--ADC)于6N 120分钟KOH在70°C]。
