在格勒诺布尔的ILL建造了一个新的3 He气体核极化加注站。“Tyrex”机器使用亚稳态交换光泵浦，在大约1毫巴的压力下极化3 He气体。然后通过液压钛合金活塞压缩机将气体压缩到几巴。该机器可提供约1.5 bar-1/h的极化气体，比1996年在ILL安装的第一个充气站增加了一个数量级。这种压缩的极化气体被用来极化用于凝聚态和基础物理实验的中子束。第一个结果，并在ILL现有的中子仪器的实施例进行了说明。(C)2004 Elsevier B. V.保留所有权利。
A new filling station for nuclear polarisation of 3 He gas has been constructed at the ILL, Grenoble. The "Tyrex" machine uses metastability-exchange optical pumping for polarising the 3 He gas at about 1 mbar pressure. The gas is then compressed up to several bars via a hydraulic titanium-alloy piston compressor. The machine can provide about 1.5 bar-1/h of polarised gas-an order-of-magnitude increase over the first filling station installed at the ILL in 1996. The compressed, polarised gas is used for polarising neutron beams for condensed-matter and fundamental physics experiments. First results are presented and examples of implementations on existing neutron instruments at ILL are described. (C) 2004 Elsevier B.V. All rights reserved.
