经过全面检修的 IN5 是第一台配备位置敏感探测器的冷中子飞行时间谱仪。它自 2008 年底开始按计划运行。使用经验证实了定性和定量效率提高的预期，为飞行时间光谱学开辟了新的机遇。充分利用位置敏感探测器的潜力，对单晶光谱的需求不断增加，而增强的计数率和更好的信噪比允许在更传统的准弹性散射领域研究更小的样品或更弱的散射体。对样品环境的额外努力——专用磁体和极化分析选项——预计将进一步提高强相关电子系统研究的潜力。
The fully overhauled IN5 was the first cold neutron time-of-flight spectrometer equipped with position sensitive detectors. It has been in scheduled operation since end of 2008. The experience of use has confirmed the expectations in terms of both a qualitative and quantitative efficiency increase, allowing to open new opportunities for time-of-flight spectroscopy. Using the full potential of the position sensitive detectors has brought up an increasing demand for single crystal spectroscopy while the enhanced count-rate and better signal-to-noise allow studying smaller samples or weaker scatterers in the more conventional field of quasi-elastic scattering. Additional effort with sample environment – dedicated magnet and polarization analysis option – are expected to improve further the potential for study of strongly correlated electron systems.
