使用氟化锂和硫化锌混合物的大面积层构建了高效的中子计数器，闪烁光通过波长移动光导传输到光电倍增管。这些计数器的阵列已组装成一个中子多重探测器，用于超重元素搜索。该阵列对裂变中子的探测效率为37±2%，中子扩散时间为83μs。当在 60 mwe 深度的地下运行时，测得的阵列背景率为 0.36+or-0.02 s-1。
Efficient neutron counters have been constructed using large area layers of a mixture of lithium fluoride and zinc sulphide, the scintillation light being transmitted to photomultipliers by wavelength shifting light guides. An array of these counters has been assembled to form a neutron multiplicity detector for use in a superheavy element search. This array had a detection efficiency for fission neutrons of 37+or-2% and a neutron diffusion time of 83 mu s. The measured background rate of the array, when operated underground at a depth of 60 mwe, was 0.36+or-0.02 s-1.
