Cryocoolers and liquid helium cooled sorption cryopumps are widely used for the
generation of high and ultra-high vacuum in large size experimental systems. Application …

SST-1 is a Superconducting Tokamak for a proposed plasma discharge of long duration. To
have plasma discharges, ultra-high vacuum is maintained in the vacuum vessel of this …

Cryosorption pumps are only possible solution to pump helium gas in Tokamak. In this
paper, we report the performance improvement of cryosorption pump, whose pumping …

To create high and ultra-high vacuum environments in large-size chambers for applications
in space research, nuclear fusion, accelerators, etc., vacuum pumps with fast pumping …

Cryosorption pumps are the only possible solution to pump helium gas in Tokamak. In
cryosorption pump, due to weak van der Walls forces the adsorbate gas molecules are held …

To achieve ultra-high vacuum in the vacuum vessel of SST-1, the baking of vacuum vessel is
done to remove impurities like water vapour, carbon-dioxide and hydrocarbons etc. The …

Scanning probe microscopy (SPM) is a useful instrument to study the surface topography of
the sample at an atomic resolution. SPM system is sensitive to vibration and contamination …

Chromium (Cr (VI) and methylene blue (MB) released from industry lead to a significant
environmental pollution and have a tendency to accumulate in a certain part of the human …
