CEA/Cadarache的剂量测定指令控制和仪器实验室（LDCI）专门从事微型裂变室（直径从8毫米到1.5毫米）的开发、设计和制造。LDCI裂变室车间的特殊性是它能够制造和分配除铀235以外的裂变沉积物（通常是钚242、钚237、铀238、钍232）的特殊裂变室。我们还能够根据堆芯测量要求定义探测器的特性：传感器几何形状、裂变存款材料和质量、填充气体成分和压力、操作模式（脉冲、电流或Campbelling）以及相关电缆和电子设备。裂变室的设计依赖于LDCI开发的数值模拟和建模工具。我们目前在裂变室应用方面的活动之一是开发使用坎贝尔模式的快中子通量仪器，专门用于材料测试反应堆中的测量。
The Dosimetry Command control and Instrumentation Laboratory (LDCI) at CEA/Cadarache is specialized in the development, design and manufacturing of miniature fission chambers (from 8 mm down to 1.5 mm in diameter). LDCI fission chambers workshop specificity is its capacity to manufacture and distribute special fission chambers with fissile deposits other than U235 (typically Pu242, Np237, U238, Th232). We are also able to define the characteristics of the detector for any in-core measurement requirements: sensor geometry, fissile deposit material and mass, filling gas composition and pressure, operating mode (pulse, current or Campbelling) with associated cable and electronics. The fission chamber design relies on numerical simulation and modeling tools developed by the LDCI. One of our present activities in fission chamber applications is to develop a fast neutron flux instrumentation using Campbelling mode dedicated to measurements in material testing reactors.
