✦ Synopsis

Once the absolute polarization of a stored proton beam is established by observing a nuclear reaction with a known analyzing power at a given energy, this calibration can be transported to a different energy since in a ring it is possible to easily change the energy of a stored sample of beam particles. This leads to a method to establish new calibration standards at arbitrary new energies. This has been demonstrated in an experiment with the Indiana Cooler.
