Abstract
The cryogenic trap of the invention comprises, in a hollow body () having an access valve () and an outlet valve (), a cold core () associated with a plate () having low thermal inertia and movable between a trapping position in contact with the cold core (), and a regeneration position spaced apart from the cold core () and in contact with a heater ring (). The plate () is in contact with gases to be trapped, and prevents them from passing to the cold core (). Regeneration requires heating only of the plate () carrying the condensed and solidified gases, and it is therefore more rapid.
