Air Safety Engineering is a service and sales company utilizing, by exclusive agreement, the equipment of Cold Jet, Inc., of Loveland OH. The Cold Jet process utilizes pellets of solid carbon dioxide as a blast media to perform various cleaning and removal operations for commercial and industrial customers. The thermal properties of the solid carbon dioxide pellets, along with their kinetic energy when propelled by a large volume high pressure stream of compressed air, provides the force to dislodge and remove contamination, residue, debris, product build up and even paint from plant areas and equipment. The process is non-abrasive and leaves only the removed materials to be disposed of. Air Safety Engineering provides a contract cleaning service, equipment sales for those who have enough use to warrant owning of the equipment and the sale of solid carbon dioxide pellets to those who purchase or lease the equipment.

The principal scientific instrument at Fermilab is the Tevatron: the final of five separate particle accelerators working in series to accelerate protons to nearly the speed of light, after which they are annihilated either by a fixed target or by a counter-rotating beam of anti-protons. The collision debris is analyzed at the large experiments located at the collision points. The Tevatron, highest in energy of the Fermilab accelerator complex, is made up of 1000 superconducting magnets used to steer the particle beam. These magnets operate at liquid helium temperatures (-450 degrees F) and are cooled by the Tevatron cryogenic cooling system (CSS), which was recently dedicated an ASME International Historic Mechanical Engineering Landmark.

The Thomas Jefferson National Accelerator Facility, Jefferson Lab is a world-class nuclear physics research laboratory used to probe the nucleus of the atom to learn more about the quark structure of matter. In order to accomplish this, Jefferson Lab employs a continuous electron beam with high energy, high current and excellent quality. The beam is accelerated in a superconducting radio-frequency accelerator based on the world's largest number of superconducting cavities, some 338 in all. The cavities are cooled by liquid helium from a 4.8 kW refrigeration plant, the world's largest at 2K. The laboratory focuses on scientific exploration as well as educating the next generation in science and sustaining partnerships with industry in a robust technology transfer program including a superconducting 1 kW Free Electron Laser. Jefferson Lab is managed and operated by the Southeastern Universities Research Association (SURA), which is a consortium of 41 universities under contract with the Department of Energy (DOE).
