研制了用于全面禁止核试验条约现场视察的移动式37Ar快速测量原型系统。进行了移动式37Ar快速测量原型系统演示活动。演示活动通过车载运输、模拟样品快速分离纯化测量、地下样品快速取样分离纯化测量、取样有效性四个场地试验和三次实验室验证测试,全面展示和验证了移动式37Ar快速测量原型系统的技术状态和性能指标。演示结果表明:移动式37Ar快速测量原型系统最小探测下限满足探测当量大于1kt的地下核试验的要求,且具有“机动、快速、小型”的特点,但系统仍需在降低探测限、增强稳定性和自动化程度等方面开展进一步研究工作。
A prototype mobile 37Ar rapid prototyping system was developed for on-site inspections of the Comprehensive Nuclear-Test-Ban Treaty. A mobile 37Ar rapid measurement prototype system demonstration was conducted. Demonstration activities Fully demonstrated and validated the technical status of the mobile 37Ar rapid prototyping system through in-vehicle transport, rapid separation and purification measurements of simulated samples, rapid sampling of underground samples, purification and measurement, sampling validity of four field tests and three laboratory tests And performance indicators. The demonstration results show that the minimum detection limit of mobile 37Ar rapid prototyping system meets the requirement of underground nuclear test with detection equivalent larger than 1kt and has the characteristics of “maneuvering, fastness and smallness”, but the system still needs to reduce the detection limit and enhance the stability And degree of automation to carry out further research work.
