Recommandation 1 du 14e CCL (2009)
Supporting key comparison CCL-K11 in national metrology laboratories
The Consultative Committee for Length,
considering that
- the key comparison of stabilized lasers has been defined by the CCL as a BIPM key comparison under the name BIPM.L-K11 in 2003,
- the BIPM organized BIPM.L-K11, started the first measurements in 2004, and ran successful comparisons of more than thirty frequency standards until the end of 2006,
- the CIPM recommended to re-organize it as a CCL key comparison under the name CCL-K11 with one pilot laboratory and several node laboratories distributed in the regions;
and aware that
- CCL-K11 has started under the new structure, with one pilot and four other node laboratories,
- these laboratories call for technical expertise from the BIPM,
- the CCL WGDM had recognized this need;
recommends that
- the BIPM provide support to the development of CCL-K11 during a transition period by allowing one of its experts on laser frequency metrology to assist the node laboratories.
