  The electric and magnetic dipole moment of charm and bottom baryons can be
measured for the first time by using bent crystal technology at the LHC. The
experimental method, proposed in recent years, suffers from limited statistics,
which dominates the uncertainty of the measurement. In this work, we present an
alternative experimental layout, based on the use of crystal lenses, that
improves the trapping efficiency by about a factor 15 (35) for a 2-cm (5-mm)
target with respect to the nominal layout, with plain crystal faces. The
efficiencies are evaluated taking into account the constraints from the LHC
machine, and the technical challenges to realize this novel experimental method
are discussed.
