大体积球形正比计数器(SPC)是一种新型的探测器,它的目标是相对较大的靶质量,具有低阈值、低本底和粒子识别的可能性,操作简单、可靠。本文介绍了这种探测器的研究进展,并在北京建立了一个原型,用于α中子测量和长期稳定运行。通过SPC原型实现了初步理解。它可以测量α和中子,并显示粒子识别能力。经长期运行表明,该探测器性能稳定,是一种性能优良的探测器。它需要更多的测试和研究,以达到更低的能量区域,更好的粒子识别,更多的了解效率等。原则上,SPC能够检测非常低能量的核反冲(在几十keV的能量范围内)和具有较低压力的较小能量,因此是稀有事件搜索的非常好的候选者。
A novel large-volume spherical proportional counter (SPC) aims at relatively large target masses with low threshold, low background, and possible particle identification, with an extremely simple and robust operation.In this paper, we present some progress on the study of such a kind of detector, with a prototype in Beijing for alpha neutron measurement and long-term running stability..Preliminary understanding was achieved with a SPC prototype. It can measure alpha and neutron and show the capability of particle identification. Long-term running of the detector shows that it is a good stable detector..It needs more tests and studies to reach lower energy region, better particle identification, more understanding of efficiency, etc..The SPC, in principle, is capable of detecting very low energy nuclear recoils (in the few tens keV energy region) and smaller energy with lower pressure, thus being a very good candidate for rare event searches.
