Vacuum technique

Long-term activities have given us practical knowledge in the following fields:

 

  • Quantitative and qualitative determination of residual gases in vacuum systems up to nucleon number 100.
  • Ultra-clear pumping of vacuum spaces using a helium cryopump designed at the institute. Pumping speed is 25 l /s for helium gas; limitary pressure 10–7 Pa is achieved without vibration and without electric power.
  • Measurement of pressure in the range of 100 Pa – 0.6 MPa in non-aggressive environment with an accuracy of 0.1 %.
  • Seeking of leakage in vacuum systems and in cooled vacuum systems, seeking for leakage for superfluid helium (λ – leakage).
