Abstract
A cryostat, comprising an outer vacuum vessel containing cryogenic equipment suspended from the outer vacuum vessel by a number of suspension rods. At least one of the suspension rods is provided with a tensioning and retaining mechanism for holding that suspension rod in tension braced against a suspension bracket). This tensioning and retaining mechanism includes a tubular rod carrier arranged, in use, to pass through a hole or slot in the suspension bracket, the rod carrier having an axial bore through which, in use, the rod may pass; a thread on its outer surface along at least part of its length; and a rod bearing surface for, in use, transmitting force to the rod. This tensioning and retaining mechanism also comprises a tensioning nut threaded onto the thread so as to, in use, brace against the suspension bracket to urge the tubular rod carrier in the direction of the rod bearing surface so as to apply tension to the rod.
