Abstract

Cold enclosure having a tubular shape, surrounding the conductors of a cryogenic connection, consisting of two layers of composite material, joined together by a metallic connection, an outer cover made of an iron and nickel alloy in which the proportion of nickel comprises between thirty and forty per cent, and an inner layer of copper or aluminum, this inner layer preventing the generating of alternating induced fields in the outer cover, which is magnetic.

Claims

1. In a cold container made of a composite material, having a tubular shape, surrounding the conductors of a cryogenic connection, comprising a casing made of an iron and nickel alloy in which the concentration of nickel comprises between thirty and forty-five per cent, the improvement wherein:

a metal screen made of a material having a resistivity lower than 3.10 8 ohms. meter surrounds the conductors inside the said casing.

2. The cold container according to claim 1, wherein:

said screen comprises a metal layer covering the inside face of the said casing.

3. The cold container according to claim 2, wherein:

said casing and the said screen are made from a laminated and bent strip comprising a first layer forming said envelope and a second layer forming said screen.
