对我国試制的大面积长塑料閃爍体的技术衰减长度进行了测量,研究了閃爍体表面和頂端是粗糙面和抛光面,包复反光物質,加不同长度光导对閃爍体的光传輸性能的影响。在不同的情况下技术衰减长度在14.1—142cm之間变化很大。
The technological attenuation length of a large area long plastic scintillator prototyped in our country was measured. The optical transmission properties of the scintillator on the scintillator surface and the top surface were studied. influences. In different circumstances, the technical attenuation length varies greatly from 14.1 to 142 cm.
