探测

Today, such patrol aircraft have radars that can pick up a schnorkel mast, although other ships have a harder time spotting the mast than they would the surfaced sub.

现在，虽然有其他的船更加难以探测到上浮潜艇的schnorkel桅杆，但有些巡逻飞机装备了可侦测到schnorkel的设备。

The first phase array ofthe AS γ experiment began to run in June 1990. The first phase array thatconsists of 49 plastic scintillate detector has an angle resolution of 1°, atrigger rate of 20Hz and a threshold energy of about 10TeV. The second phasearray was finished on the base of the first phase array in 1994, and after that, apart of the second phase array was made high density.

一期阵列由49个塑料闪烁体探测器组成，探测阈能为10TeV左右，事例触发率为20Hz，角分辨率小于1°。1994年在一期阵列的基础上进行了扩建，扩建后阵列比一期阵列有效面积增大8倍，随后进行了部分加密，建成二期／加密阵列。

The structure of the large area scintillating fiber array detector and the characteristics of the scintillating fibers unit were described.
