【摘要】 设计了一套用于仪器中子活化分析(INAA)的新型自动换样系统。整个系统由组态王KingView6.55软件控制,其中自动进样装置每次可装载200个样品,且具有样品自动排队循环测量功能。样品转换器替换了原三叉管,并同时可为三套HPGe探测器提供传输待测样品。在传输管道关键节点上安装有光电传感器,实现了样品传输过程的实时监测,提高了样品传输的可靠性。更多还原

【Abstract】 A new automatic sample changer system used in instrumental neutron activation analysis has been designed,which is controlled by kingview6. 55 software. The automatic sample loading system which has a capacity of 200 samples each time can realize automatic loop queuing for next counting again. The old three- joint tube is replaced by the sample changer that can be used to simultaneously transfer samples for three sets of HPGe detectors. Meanwhile,optical sensors fixed in the key point of tube can monitor the sample transfer process that ensures the reliability of sample transmission.更多还原
