Applying Resonant Spin Flippers with Poleshoes and Longitudinal Radio Frequency Fields to Time of Flight MIEZE

A time of flight MIEZE spectrometerstudyis presented. The instrumentuses solenoid radio frequency(RF)spin flipperswithsquare pole shoes and a magnetic yoke. These flippers can achieve higherstaticfields than conventional resonant RF spin flippers, which employ an air core.High fields are crucial for the construction of a high resolution and compact MIEZE spectrometer.Using both types of flipperstwo MIEZE spectrometer configurationsare constructed and comparedon the same beam line. It was demonstratedthat the pole shoe/solenoid coil RF flipperscan achieve a MIEZE signal, which is similarin quality to theconventionalreferencesetup.The highest obtained modulation frequency was 100kHz.
