This study developed a manufacturing process that uses the doctor blade method for printing of neutron activation foil arrays. The doctor blade method addresses some of the limitations of other thick-film electrode printing techniques, including printing failure. Printed activation arrays of 9,216 and 36,864 foils arranged within a 10 cm × 10 cm area were prepared using the doctor blade method to improve the measurement accuracy of the neutron spatial distribution. Mass values were measured within 1% variation, indicating uniformity of mass distribution. No printing failure other than simple defects was observed. Moreover, this relatively simple process offers excellent mass-production potential.

本研究开发了一种使用刮刀法打印中子激活箔阵列的制造工艺。刮刀法解决了其他厚膜电极印刷技术的一些局限性，包括印刷失败。使用刮刀法制备了排列在 10 cm × 10 cm 区域内的 9,216 和 36,864 个箔的印刷激活阵列，以提高中子空间分布的测量精度。质量值在 1% 的变化范围内测量，表明质量分布的均匀性。除了简单的缺陷外，没有观察到打印失败。此外，这个相对简单的过程提供了极好的大规模生产潜力。
