  The UA9 setup, installed in the Super Proton Synchrotron (SPS) at CERN, was
exploited for a proof of principle of the double-crystal scenario, proposed to
measure the electric and the magnetic moments of short-lived baryons in a
high-energy hadron collider, such as the Large Hadron Collider (LHC). Linear
and angular actuators were used to position the crystals and establish the
required beam configuration. Timepix detectors and high-sensitivity Beam Loss
Monitors were exploited to observe the deflected beams. Linear and angular
scans allowed exploring the particle interactions with the two crystals and
recording their efficiency. The measured values of the beam trajectories,
profiles and of the channeling efficiency agree with the results of a
Monte-Carlo simulation.
