✦ Synopsis

NUMEROUS devices for irradiation in liquid nitrogen in atomic piles have already been described in the literature. They employ, in general, commercial nitrogen, or, if they use very pure nitrogen, they have a nitrogen circulation arrangement to enable the nitrogen to condense outside the pile.

The device we are going to describe here is cheaper to make and very reliable in operation. We shall first recapitulate the difficulties presented by the use of nitrogen in atomic piles, and some of the devices which have already been employed to overcome these difficulties. We shall then list the results obtained with the cold loop designed by us.
