What are the four basic rules for working under HV and UHV conditions?
When working with high vacuum (HV) and ultra-high vacuum (UHV), there are specific aspects to consider ensuring an efficient and safe system.
To clarify, the pressure range of UHV conditions are defined as between 10-7 and 10-12 mbar, whereas HV conditions are defined as between 10-3 and 10-7 mbar. Some of the main applications of HV include metallurgical processes, nuclear physics, space simulation and analytical instruments. On the other hand, UHVs are used for surface analysis, in high-energy physics and Molecular Beam Epitaxy (MBE).
Here are the four main considerations you need to bear in mind when working under HV or UHV conditions.
