摘要

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。

Electromagnetic calorimetry using scintillating plastic fibres

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 $σ_{E} /√E⋍9.8 and 7.8%$ 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.
