Documents

Status, summary:

November 2014

  • Detailed mockup measurements with C6K: cooling properties very close for C6F14
  • The expected radiation damage to C6K in SciFi is very small, at 1-10 ppm level.
  • The pilot study has to focus on chemical properties of C6K: reactivity with water and potential filters
  • Irradiation and radiolysis study will be next step in 2015
    • new test containers
    • mixed irradiation at CHARM
    • gamma irradiation at GIF++
