Webb26 maj 2024 · Ketterle's team trapped sodium atoms using Ioffe–Pritchard magnetic traps and then used radio-frequency evaporative cooling to obtain cooler atomic gases. The atomic gases were transported to a separate chamber—the scientific chamber—using optical tweezers [ 64 ], a system for manipulating cold atoms using the force of light. Webb8 maj 1998 · Our trap consists of a clip-like coil, which generates a pure two-dimensional (2D) quadrupole field for radial confinement. The axial confinement is provided by two plane pinch coils inside the clip-coil. These two coils create a bottle field.

Webb30 maj 2024 · At an appropriate rotation frequency the trapping potential is simply the time average of the orbiting potential. The Ioffe–Pritchard trap on the other hand is designed to have a static, non-zero field minimum. In radial(x,y)directions the atoms are confined by a quadrupole field. WebbFurther details of Ioffe-Pritchard magnetic traps are discussed in Sec 2.3.2 of [47] and Ch. 5. of [62]. Fig. 12 is representative of the magnetic trap circuit. Webb(2024) Pritchard et al.
