    Poster Presentation

    In this paper, a set of dry vacuum pumps suitable for a 500W @2K helium refrigerator were investigated. Process flow diagram and the control strategies of a set of dry vacuum pumps were designed. The Experiments including the mass flow rate and pressure ratio of a set of dry vacuum pumps with the air and helium gas were tested. The input pressure of 40 kPa and output pressure of 1.05~1.1 bara...

    Poster Presentation

    The Korea Superconducting Tokamak Advanced Research (KSTAR) has been operated for the basic research of fusion energy and its 11th campaign was performed in 2018. It was necessary to construct new cryogenic facility in order to operate the KSTAR ancillary system for the advancement of KSTAR plasma performance. The KSTAR Upgraded HElium supply System (UHES) was constructed in 2016 which is...

  3. 698. C2Po1G-04 [41]: JLab Chl1 2K Cold Box Replacement
    Mrs Shirley Yang (Jefferson Lab)
    23/07/2019, 09:00
    Poster Presentation

    There is growing evidence showing that the cold compressors in the Modified Sub-atmospheric Cold Box (SC1/SCM) of the JLab Central Helium Liquefier (CHL) are approaching the end of their life. Their replacement parts are no longer available due to obsolescence, thus placing the Physics program at serious risk. A new sub-atmospheric cold box (SC1R), which hosts five technologically superior,...

  4. 796. C2Po1G-05 [42]: Commissioning Plan for LCLS II 2K Cold Box
    Ritendra Bhattacharya (Thomas Jefferson National Accelerator Facility)
    23/07/2019, 09:00
    Poster Presentation

    Commissioning of the LCLS II cryogenic plant has been planned with respect to electrical and mechanical systems checkout, equipment cleanup, cool-down, and individual performance evaluation. This plant consists of warm and cold storage, helium compressors, 4.5 K and 2 K cold boxes, and all auxiliaries typical for helium refrigeration processes. The 2 K cold box, consisting of five cold...
