Stanford Team to Participate in ESA Study of Clock Missions

A proposal from John Lipa of Stanford University to the European Space Agency (ESA) to fly a superconducting cavity oscillator on the International Space Station to link up with the French laser-cooled-atom clock ACES was recently accepted for study. This proposal was competitively selected as part of the call for proposals for the F2/F3 ESA missions now on the drawing boards. With the recent acceptance of a similar type of mission (Superconducting Microwave Oscillator - SUMO) by the Fundamental Physics Discipline of NASA's Code UG, the focus of the ESA study will be more on providing a high-quality microwave link to the ACES payload.

The ESA interest in the cavity oscillator attests to the high level of international interest in fundamental clock experiments in space. The Stanford team looks forward to a productive partnership with the atomic physics community in bringing about new measurements of scientific interest, and serving the community at large.
