Optimizing the intensity and purity of a Zeeman-decelerated beam [PDF]
Review of Scientific Instruments, 2021 A pure, state-selected beam of gas-phase radicals is an important tool for the precise study of radical reactions that are astrochemically and atmospherically relevant.

Zeeman deceleration beyond periodic phase space stability
New Journal of Physics, 2017 In Zeeman deceleration, time-varying spatially inhomogeneous magnetic fields are used to create packets of translationally cold, quantum-state-selected paramagnetic particles with a tuneable forward velocity, which are ideal for cold reaction dynamics ...

Zeeman deceleration of electron-impact-excited metastable helium atoms
New Journal of Physics, 2015 We present experimental results that demonstrate—for the first time—the Zeeman deceleration of helium atoms in the metastable 2 ^3 S _1 state. A more than 40% decrease of the kinetic energy of the beam is achieved for deceleration from 490 m s ^−1 to a ...

Zeeman deceleration of methyl radical
, 2014 Conventional Zeeman decelerator, consisting of 80 stages, was constructed and tested. The experimental setup was characterized using O₂ as the reference molecule. Known results of deceleration of O₂ were reproduced.

Towards the study of cold chemical reactions using Zeeman decelerated supersonic beams [PDF]
, 2014 Zeeman deceleration is an experimental technique which allows for the manipulation of open-shell atoms and molecules in a supersonic beam thus producing mK-cold, velocity-tunable beams of particles in selected quantum states.

Evolutionary Algorithm Optimization of Zeeman Deceleration: Is It Worthwhile for Longer Decelerators? [PDF]
J Phys Chem A, 2019 In Zeeman deceleration, only a small subset of low-field-seeking particles in the incoming beam possess initial velocities and positions that place them within the phase-space acceptance of the device. In order to maximize the number of particles that are successfully decelerated to a selected final velocity, we seek to optimize the phase-space ...

Low-Energy Collisions of Zeeman-Decelerated NH Radicals with He Atoms. [PDF]
J Phys Chem A, 2023 We report an experimental study of state-to-state inelastic scattering of NH (X 3Σ-, N = 0, j = 1) radicals with He atoms. Using a crossed molecular beam apparatus that combines a Zeeman decelerator and velocity map imaging, we study both integral and differential cross sections in the N = 0, j = 1 → N = 2, j = 3 inelastic channel. We developed various

High-resolution imaging of molecular collisions using a Zeeman decelerator [PDF]
, 2023 In this doctoral research a Zeeman decelerator was employed to obtain precise control over magnetic particles and prepare them for cold and controlled molecular collision experiments in a crossed-beam setup. Combined with an improved velocity map imaging
