Letter of Intent: AICE -- 100m Atom Interferometer Experiment at CERN Open
We propose an O(100)m Atom Interferometer (AI) experiment -- AICE -- to be installed against a wall of the PX46 access shaft to the LHC. This experiment would probe unexplored ranges of the possible couplings of bosonic ultralight dark mat…
