Model for the overall phase-space acceptance in a Zeeman decelerator [PDF]

Physical Review A, 2015
We present a new formalism to calculate phase-space acceptance in a Zeeman decelerator. Using parameters closely mimicking previous Zeeman deceleration experiments, this approach reveals a hitherto unconsidered velocity dependence of the phase stability ...

High-resolution imaging of molecular collisions using a Zeeman decelerator [PDF]

Journal of Chemical Physics, 2020
We present the first crossed beam scattering experiment using a Zeeman decelerated molecular beam. The narrow velocity spreads of Zeeman decelerated NO (X2Π3/2, j = 3/2) radicals result in high-resolution scattering images, thereby fully resolving quantum diffraction oscillations in the angular scattering distribution for inelastic NO–Ne collisions and

Multistage Zeeman decelerator for molecular-scattering studies [PDF]

Physical Review A, 2017
We present a new concept for a multi-stage Zeeman decelerator that is optimized particularly for applications in molecular beam scattering experiments. The decelerator consists of a series of alternating hexapoles and solenoids, that effectively decouple the transverse focusing and longitudinal deceleration properties of the decelerator.

Zeeman deceleration of H and D

Physical Review A, 2007
Hydrogen and deuterium atoms in supersonic jet expansions have been decelerated using a multistage Zeeman decelerator. The properties of the decelerator have been completely characterized in a series of experiments in which (i) the initial longitudinal velocities of the decelerated atoms, (ii) the maximum magnetic field strength, and (iii) the duration

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

Review of Scientific Instruments, 2019
Zeeman deceleration is a relatively new technique used to obtain full control over the velocity of paramagnetic atoms or molecules in a molecular beam. We present a detailed description of a multistage Zeeman decelerator that has recently become operational in our laboratory [Cremers et al., Phys. Rev.

Zeeman deceleration of metastable nitrogen atoms

Journal of Physics B: Atomic, Molecular and Optical Physics, 2016
In a proof-of-principle experiment, we show that the longitudinal velocity of a supersonic beam of nitrogen atoms in the metastable 2D state can be decreased from 460 to 410 m s−1 using a 12-stage Zeeman decelerator. The experimental results are in good agreement with three-dimensional numerical particle trajectory simulations.

Multistage Zeeman deceleration of hydrogen atoms

Physical Review A, 2007
The deceleration of beams of neutral particles possessing an electron spin with time-dependent inhomogeneous magnetic fields is demonstrated experimentally. Half the kinetic energy of a velocity-selected part of a pulsed supersonic beam of hydrogen atoms in the ground state is removed using six pulsed magnetic field stages.

STARK AND ZEEMAN DECELERATION OF NEUTRAL ATOMS AND MOLECULES

Laser Spectroscopy, 2008
Argon and hydrogen atoms excited to Rydberg Stark states in supersonic expansions have been decelerated using inhomogeneous electric fields. In the case of hydrogen, the atoms have been decelerated from an initial velocity of 700 m/s to zero velocity in the lab frame using time-dependent inhomogeneous electric fields and subsequently stored in two- and
