A new design for a traveling-wave Zeeman decelerator: II. Experiment

A novel traveling-wave Zeeman decelerator based on a double-helix coil geometry capable of decelerating paramagnetic molecules with high efficiency is presented. Moving magnetic traps are generated by applying time-dependent currents through the coils. Paramagnetic in low-field-seeking states confined inside moving which decelerated to lower forward velocities. As prototypical example, we demonstrate deceleration OH radicals from an initial velocity 445 m s?1 down various final The experimental results analyzed and numerically reproduced help trajectory simulations confirming phase-space stability new device.
