ABSTRACT:
A vacuum container of a radiation image multiplier tube is disclosed, which is provided with a radiation input window made of Al or an Al alloy and an output portion made of a glass or ceramic insulator for outputting radiation image multiplied signals. Between the input window and the output portion is interposed a ring made of Fe or an Fe alloy, and an airtight joint between the ring of the input window is effected by hot pressure-bonding through a thin layer of Ni, Cu or Al. A method of manufacturing the vacuum container by means of such hot pressure-bonding is also disclosed.
