我们测量了超冷中子（UCN）通过内部涂有高光学势材料的管子的传输。用铍涂层石英波导获得了归一化到1 m长UCN波导的最佳透射率T值，T=（99.0±1.0）%。此外，发现（i）涂覆有NiMo的玻璃管（88/12），T=（97.3 ±0.6）%，（ii）通过复制技术制备的NiMo（85/15）波导，T=（97.1 ±0.8）%和（iii）涂覆有NiMo的玻璃波导（82/18），T=（96.3 ±2.1）%的优异透射系数。结果表明，由涂层玻璃管制成的UCN波导具有与复制技术相同的优良传输特性。然而，它们要便宜得多。
We have measured the transmission of ultra-cold neutrons (UCN) through tubes coated on the inside with materials of high optical potentials. The best transmission value,T, normalised to 1 m long UCN guides was obtained with a beryllium coated quartz guide,T=(99.0±1.0)%. Furthermore, excellent transmission coefficients were found for (i) a glass tube coated with NiMo(88/12),T=(97.3 ±0.6)%, (ii) a NiMo(85/15) guide made by the replication technique,T=(97.1 ±0.8)% and (iii) a glass guide coated with NiMo(82/18),T=(96.3 ±2.1)%. The results demonstrate that UCN guides made from coated glass tubes have the same excellent transmission properties as those produced with the replication technique. They are, however, significantly cheaper.
