我们目前的设计研究，测试测量的结果，和蒙特卡罗模拟，作为实现大面积中子探测器（LAND）的基础。它的正面面积为2 m x 2 m，深度为1 m，采用被动转换器和主动闪烁体材料的多层结构。探测器被细分为独立操作的桨，允许飞行时间和位置测量。对于15 m的飞行路径，能量分辨率为Δ T（n）/ T（n）= 5.3%，对于T（n）几乎等于1 GeV的中子，预计总探测效率几乎等于1。介绍了LAND在GSI SIS装置上的运行情况。
We present design studies, results of test measurements, and Monte Carlo simulations which served as a basis for the realization of a large area neutron detector (LAND). It has a front area of 2 m x 2 m and a depth of 1 m, and features a multilayer structure of passive converter and active scintillator material. The detector is subdivided in independently operating paddles which allow time-of-flight and position measurement. An energy resolution of DELTA-T(n) / T(n) = 5.3% for a flight path of 15 m and an overall detection efficiency of epsilon almost-equal-to 1 is anticipated for neutrons with T(n) almost-equal-to 1 GeV. The operation of LAND at the SIS facility of GSI is described.
