Radiator vessel

Here follows a summary of the parameters of the radiator vessels of the two COMPASS RICH's:

  1. Volume: 25 tex2html_wrap_inline3040 for RICH1, 55 tex2html_wrap_inline3040 for RICH2
  2. Materials: no radiator pollution (purity better than 5 ppm for tex2html_wrap_inline3044 and tex2html_wrap_inline3046 has to be achieved)
  3. Mechanical structure: gas tight matching with photon detectors
    provide supports for photon detectors
    closing system in front of the photon detectors
