ultra high vacuum

What are the Challenges in Maintaining UHV?

Maintaining UHV conditions is challenging due to:
Leaks: Even the smallest leaks can introduce contaminants. Precision in sealing and welding is crucial.
Outgassing: Materials inside the vacuum chamber can release gases over time. Continuous pumping and material selection help mitigate this.
Instrumentation Sensitivity: Instruments used in UHV must be highly sensitive and capable of operating under such conditions without introducing additional contaminants.
