Unit S3 of the Hughes Vuilleumier (VM) Cryocooler Program has undergone accelerated life testing at twice the service speed expected in a normal unit. Debris samples were obtained from all areas of the cooler; samples of the regenerator balls were collected from the second and third stages only. The debris has been identified by an investigative analysis using the analytical techniques of X-ray diffraction, IMMA, and SEM/EDXS. Most of the particulates contain a combination of Iron, Chromium, and Nickel or Molybdenum Niobium compounds.
