CNS:                          one vertical since 1986, not operating these days
one horizontal in a beam tube for testing cold moderators

moderator:                 D2+ X% H2                temperature:             20 K

volume:                      0.5 L                          phase:            sub-cooled liquid

power:                        4000 W, used for either the vertical or the horizontal CNS

refrigerator                Brayton cycle, 2 turbines, piston compressors

heat removal:            gravity thermal siphon + direct cooling

--------------------------

Remarks:                   vertical source was used for polarised VCN and UCN production.

                                    There is also a horizontal solid D2 source.

                                    There are plans for a new CNS + guide hall
