论文摘要
Amore的协作搜索具有超高光ad的moleybdate晶体的100mO中性链双β衰减，以低温闪烁的侧强度进行操作。对于如此罕见的事件搜索实验，研究和减少探测器材料中的放射性背景污染物的技术至关重要。本文讨论了富集钼的深度纯化技术，以生长晶体的生长，并在生长钼酸锂晶体后从留下的残留熔体中恢复100moo3。用ICP-MS测试了纯化和回收粉末之前和之后的三氧化钼粉的纯度；提出了这些测试的结果。
The AMoRE collaboration searches for the neutrinoless double-beta decay of 100Mo with ultra-radiopure molybdate crystals operated as low-temperature scintillating bolometers. For such a rare event search experiment, the techniques for investigating and reducing radioactive background contaminants in detector materials are extremely crucial. This paper discusses techniques for deep purification of enriched molybdenum for growing the crystals and the recovery of 100MoO3 from the residual melt left after growing lithium molybdate crystals. The purities of enriched molybdenum trioxide powders before and after the purification and that of the recovered powder were tested with ICP-MS; results of these tests are presented.
