Abstract
When used in lead-scintillator sandwich calorimetry, scintillating optical fibres offer a new way to achieve fine grain sampling and thereby to improve the energy and spatial resolution of a technique still unbeaten for timing and compactness. A small calorimeter element made of planes of 0.9 mm diameter fibres alternating with Pb plates has been built and tested in an electron beam. An energy resolution of was obtained with 1 and 0.5 mm Pb plates, respectively. The parameters of the fibres have been measured. Calculations performed with a refined version of the EGS code reproduce these results and suggest improved Pb-fibre calorimeters rivalling with Pb glass in energy resolution.
当用于铅-闪烁体夹层量热法时，闪烁光纤提供了一种实现细颗粒采样的新方法，从而提高了能量和空间分辨率，这是一种在时序和紧凑性方面仍然无与伦比的技术。一个由直径0.9毫米的纤维平面与铅板交替构成的小型量热计元件已被制造出来，并在电子束中进行了测试。在1 mm和0.5 mm Pb板上，能量分辨率分别为σE/√E⋍9.8和7.8%。对纤维的参数进行了测量。使用改进版本的EGS代码进行的计算再现了这些结果，并提出改进的铅纤维量热计在能量分辨率上可与铅玻璃相媲美。
