Design and construction of a multistage Zeeman decelerator for crossed molecular beams scattering experiments

摘要: Zeeman deceleration is a relatively new technique used to obtain full control over the velocity of paramagnetic atoms or molecules in molecular beam. We present detailed description multistage decelerator that has recently become operational our laboratory [Cremers \emph{et al.}, Phys. Rev. A 98, 033406 (2018)], and specifically optimized for crossed beams scattering experiments. The consists an alternating array 100 solenoids permanent hexapoles guide decelerate molecules. features modular design mechanically easy extend arbitrary length, allows solenoid hexapole elements are convenient replace. associated electronics efficiently water cooled allow operate at repetition rates exceeding 10 Hz. characterize performance using various metastable rare gas atoms. Imaging exit reveals transverse focusing properties decelerator.
