强子和喷注能量和动量的高精度测量是未来高能对撞机实验中探测器面临的主要挑战之一。目前，为实现这一目标考虑了两种方法。在粒子流方法（PFA）中，需要一个复杂的高度分段的量热计系统来识别和跟踪射流中的所有粒子。另一方面，在活动介质中的闪烁和切伦科夫光的双重读出记录允许在事件的基础上提取总簇射能量的电磁部分。重结晶纤维晶体生产方法的最新进展为基于双读出原理的均匀但精细结构的量热计的设计提供了有趣的前景。本文报道了重结晶纤维生产的最新进展。它提出了一种基于这种技术的量热计概念，该技术允许同时高精度地测量全套簇射参数，例如能量沉积的方向、空间分布及其在电磁、带电和中性强子含量方面的组成。
High precision measurement of hadrons and jet energy and momentum is one of the main challenges for detectors at future high energy collider experiments. Currently, two approaches are considered to achieve this goal. In the particle flow approach (PFA), a complex highly segmented calorimeter system is required to identify and to track all particles in a jet. On the other hand the dual readout recording of both scintillation and Cerenkov light in an active medium allows extracting the electromagnetic fraction of the total shower energy on an event by event basis. Recent progress in heavy scintillating fiber crystal production methods offer interesting perspectives for the design of a homogeneous but finely structured calorimeter based on the dual readout principle. This paper reports on recent developments in the production of heavy scintillating crystal fibers. It presents a calorimeter concept based on such technology that allows for a simultaneous high precision measurement of the complete set of shower parameters such as the direction, the spatial distribution of the energy deposition and its composition in terms of electromagnetic, charged and neutral hadrons content.
