A Liquid-Hydrogen Reactor Irradiation Device
Low-temperature irradiation devices are used with increasing frequency, especially to study radiation-induced defects in solids. A liquid-nitrogen irradiation device, which has operated for over 15,000 hours, has been described previously . However, certain defects anneal out or are transformed well below 77 °K and their study requires irradiation at lower temperatures. Two liquid-helium [2–4] and one liquid-hydrogen  reactor irradiation devices have been reported in the literature. This paper describes an irradiation device at the temperature of boiling neon, which was installed in the Mélusine swimming-pool reactor of the Nuclear Research Center of Grenoble.
