First tests of a MIEZE (modulated intensity by Zero effort)-type instrument on a pulsed neutron source

In this paper we report the results of our first tests of a novel proof-of-principle instrument developed at the IPNS, Argonne. The experiment was performed on the time of flight POSY1 instrument, the polarized reflectometer at the IPNS, which was modified to accommodate the apparatus. Two sets of RF-flippers were tested together, generating a modulated intensity by zero effort (MIEZE)-type neutron resonant spin echo signal which was observed at the detector using a wide neutron wavelength band.
