The task of the Cryogenics Laboratory and Test Stations (LCSE) is to develop expertise in cryogenics technology for superconducting magnets, accelerator cavities, physics detectors (cryogenic target systems, calorimeters), and the production and distribution of liquid helium. This expertise is applied to the design, construction, and operation of cryogenic facilities of various types and sizes. Fluids currently in use include helium, nitrogen, argon and hydrogen. Design and construction work is mainly focused on cryostats and associated cryodistribution systems, together with low temperature refrigeration machines, ranging from cryogenerators to high-power helium refrigerators.
The laboratory operates a number of test and characterization facilities stations offering a total of sixteen distinct systems for the study of the mechanical, thermal and electrical properties of materials such as insulators, composites, metallic alloys and superconductors under the influence of cryogenic temperatures and magnetic fields. Tests of cryogenic samples and subassemblies ranging in size from a few millimeters to several meters can also be carried out under nominal conditions.
A range of R&D activities is also carried out in the fields of low temperature heat transfer (helium II in a porous medium), two-phase flows (convection using helium I, nitrogen, etc.), and instrumentation development.
As of December 31, 2012, the laboratory had a staff of thirteen engineers, thirteen technicians, and one PhD student.
