Principles and Design of a Zeeman–Sisyphus Decelerator for Molecular Beams
We explore a technique for decelerating molecules using a static magnetic field and optical pumping. Molecules travel through a spatially varying magnetic field and are repeatedly pumped into a weak-field seeking state as they move towards each strong field region, and into a strong-field seeking state as they move towards weak field. The method is time-independent and so is suitable for decele...
متن کاملMultistage Zeeman deceleration of metastable neon.
A supersonic beam of metastable neon atoms has been decelerated by exploiting the interaction between the magnetic moment of the atoms and time-dependent inhomogeneous magnetic fields in a multistage Zeeman decelerator. Using 91 deceleration solenoids, the atoms were decelerated from an initial velocity of 580 m/s to final velocities as low as 105 m/s, corresponding to a removal of more than 95...
متن کاملHanle-Zeeman scattering matrix
A theory is presented that allows the Mueller matrix for coherent scattering to be calculated for arbitrary magnetic fields, atomic multiplets, and scattering transitions (Rayleigh or Raman scattering). For the special case of a normal Zeeman triplet (a J = 0 → 1 → 0 scattering transition) a compact analytical form for the scattering matrix is given, which allows us to better see how the variou...
متن کاملMagnetic trapping of hydrogen after multistage Zeeman deceleration.
We report the first experimental realization of magnetic trapping of a sample of cold radicals following multistage Zeeman deceleration of a pulsed supersonic beam. H atoms seeded in a supersonic expansion of Kr have been decelerated from an initial velocity of 520 m/s to 100 m/s in a 12-stage Zeeman decelerator and loaded into a magnetic quadrupole trap by rapidly switching the fields of the t...
متن کاملGetting a grip on the transverse motion in a Zeeman decelerator.
Zeeman deceleration is an experimental technique in which inhomogeneous, time-dependent magnetic fields generated inside an array of solenoid coils are used to manipulate the velocity of a supersonic beam. A 12-stage Zeeman decelerator has been built and characterized using hydrogen atoms as a test system. The instrument has several original features including the possibility to replace each de...
