Magnetic Field Fluctuations in Sc Dipole Magnet
Magnetic field fluctuations at the betatron frequency can lead to emittance growth in circular accelerators. Tolerances are extremely tight for large hadron colliders like LHC and VLHC[1]. We performed experimental studies of the fluctuations in a stand-alone superconducting Tevatron magnet. Here we give a general description of the experimental set-up, present main results and discuss conseque...
متن کاملObservation of dipole-dipole interaction in a degenerate quantum gas.
We have investigated the expansion of a Bose-Einstein condensate of strongly magnetic chromium atoms. The long-range and anisotropic magnetic dipole-dipole interaction leads to an anisotropic deformation of the expanding chromium condensate which depends on the orientation of the atomic dipole moments. Our measurements are consistent with the theory of dipolar quantum gases and show that a chro...
متن کاملStable High Beta Plasmas Confined by a Dipole Magnetic Field
Stable high-beta plasma is created and confined by the magnetic field of a superconducting coil that is suspended within a large vacuum chamber by thin supports. Discharges containing trapped electrons form when microwaves cause strong perpendicular heating at cyclotron resonance. At low gas fueling rates, an instability appears that resonates with the magnetic drifts of fast electrons and caus...
متن کاملUltrafast fluorescent decay induced by metal-mediated dipole-dipole interaction in two-dimensional molecular aggregates.
Two-dimensional molecular aggregate (2DMA), a thin sheet of strongly interacting dipole molecules self-assembled at close distance on an ordered lattice, is a fascinating fluorescent material. It is distinctively different from the conventional (single or colloidal) dye molecules and quantum dots. In this paper, we verify that when a 2DMA is placed at a nanometric distance from a metallic subst...
متن کاملResonant electric dipole-dipole interactions between cold Rydberg atoms in a magnetic field
Laser-cooled Rb atoms were optically excited to 46d5/2 Rydberg states. A microwave pulse transferred a fraction of the atoms to the 47p3/2 Rydberg state. The resonant electric dipole-dipole interactions between atoms in these two states were probed using the linewidth of the two-photon microwave transition 46d5/2 -47d5/2. The presence of a weak magnetic field 0.5 G reduced the observed line bro...
