Multistage Zeeman deceleration of hydrogen atoms
Physical Review A, 2007The 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, 2008Argon 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

Slow beams of atomic hydrogen by multistage Zeeman deceleration
Journal of Physics B: Atomic, Molecular and Optical Physics, 2008Hydrogen atoms seeded in a supersonic expansion of Kr have been decelerated from an initial velocity of 435 m s−1 to 107 m s−1 in a multistage Zeeman decelerator. The operation of the decelerator has been fully quantified by numerical particle trajectory simulations and independent measurements of the velocity distribution by ion time-of-flight mass ...

Multistage Zeeman deceleration of NH $X\,^3Σ^-$ radicals
2018We report on the Zeeman deceleration of ground-state NH radicals, using a decelerator that consists of 100 pulsed solenoids and 100 permanent hexapoles. Packets of state-selected NH ($X\,^3Σ^-$, N=0, J=1) radicals are produced with final velocities ranging between 510 m/s and 150 m/s.

Adiabatic following conditions for the deceleration of atoms with the Zeeman tuning technique
Optics Communications, 1990Abstract We present a study of the decelaration of atoms with the Zeeman tuning technique which allows us to investigate the conditions for the adiabatic following of atoms in an inhomogeneous magnetic field. The atomic motion is described in an accelerated frame of reference and two possible solutions are found for the atomic velocity, one being ...

Abstract We present a study on the process of atomic deceleration in the Zeeman tuning technique when a fluctuating laser is used. The characterization of the deceleration is made through the analysis of velocity trajectories (k v(z)) from integration of the averaged equation of motion obtained from the Bloch optical equations.
