This work demonstrates a vacuum system design that preserves materials under UHV conditions, suggesting efficient transport solutions.
Our works concerns the attainment of UHV pressures by using the non evaporable getter (NEG) pump in conjunction with turbomolecular or ion pump of small size. Studies related to surface science show that vacuum conditions in the range of UHV (10-¹⁰mbar) are required for very reactive materials, such as niobium or titanium elements. It is a very common practice to perform some surface treatments on these materials and then facing with the problem to preseve the surface state so created from the atmospherical contamination for long times (storing, transport from one laboratory to another, etc.) The aim of this work is to find a vacuum system that is easy to construct, inexpensive and almost completely free from any kind of power supply.
