在柏林亥姆霍兹中心BER-2研究反应堆建造新的中子成像仪，大大提高了该设施的潜力。该设施的重新设计包括改进中子提取和运输系统，更有效的屏蔽和创新的仪器。中子导管出口处的冷中子通量增加了一个以上的数量级，这允许实施需要单色或偏振束的方法，从而能够利用非传统的对比机制，如相位，衍射和磁对比。改进的仪器设计还通过在样品位置提供增加的束强度来促进高分辨率中子断层摄影的发展。
The construction of the new neutron imaging instrument at the BER-2 research reactor of the Helmholtz-Zentrum Berlin has greatly increased the potential of the facility. The redesign of the facility included improvements of the neutron extraction and transportation systems, more effective shielding, and innovative instrumentation. The cold neutron flux at the neutron guide exit was increased by more than one order of magnitude, which allowed for an implementation of methods that require monochromatic or polarized beams, thus enabling the exploitation of nonconventional contrast mechanisms such as phase, diffraction and magnetic contrasts. The improved instrument design also facilitates the development of high-resolution neutron tomography by providing an increased beam intensity at the sample position.
