A Superconducting Microwave-Cavity Lock for the International Space Station

Dr. Joel A. Nissen
Senior Research Physicist, High Energy Physics Laboratory (HEPL), Stanford University


With the approach of the Space Station era new interest has been kindled in performing fundamental physics experiments in space with time scales of months.Recently a superconducting microwave cavity clock experiment (SUMO) was selected for flight to perform experiments in relativity.The project has four main goals: an improved test of Local Position Invariance, improved Kennedy-Thorndyke and Michelson-Morley type experiments,and an enhancement of the performance of atomic clocks being developed elsewhere for use on the space station.In order to take full advantage of the various clocks being developed, they will need to be linked by laser telecommunication.
