Development of ultrathin solid/liquid hydrogen target using nano-thin foil.

对 Nano Membrane 提供的厚度为 200 nm 的超薄箔进行了研究。然而，人们发现它的物理强度不足以将氢限制在真空中。测试了厚度为3.6μm的MICTRON箔（TORAY），这是市售的最薄的非金属箔。微米窗在一定的内压值下会凸出；然而，它能承受高达2个大气压的压差。在低于18K的温度下，压力为423 hPa的氢气被限制在电池内并成功完全液化。物理强度几乎相当于12μm的发光箔，其杨氏模量为4GPa。

The ulrathin foil with a thickness of 200 nm provided by Nano Membrane was investigated. However, it was found not to be strong enough physically for confining hydrogen in the vacuum. A MICTRON foil(TORAY) with the thickness of 3.6μm was tested, which was the thinnest nonmetallic foil commercially available. The mictron window bulged out at the certain values of the inner pressure ; however, it withstood pressure difference up to 2 atmosphere. Below the temperature of 18K, hydrogen at the pressure of 423 hPa was confined to the cell and fully liquefied successfully. The physical strength is almost equivalent to 12μm luminor foil, whose young's modulus is 4GPa.
