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

研究了由纳米膜提供的厚度为200nm的超薄薄膜。然而，人们发现它的物理强度不足以将氢限制在真空中。测试了一种厚度为3.6μm的MICTRON （TORAY）箔，这是目前市面上最薄的非金属箔。当内压达到一定值时，微波窗口凸出；然而，它承受了高达2个大气压的压力差。在18K以下，氢气在423 hPa的压力下被限制在电池内并成功完全液化。其物理强度与12μm发光箔基本相当，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.
