Production of large-volume negative-ion source using multistring-type CF4 magnetized plasma

RF Cavity Breakdown in External Magnetic Field

Neutrino Factories and Muon Colliders’ cooling lattices require both high gradient rf and strong focusing solenoids. Experiments have shown that there may be serious problems operating rf in the required magnetic fields. It is proposed that electrons emitted from asperities on one side of a cavity are focused by the magnetic field to the other side where they damage the cavity surface in small ...

Interplanetary magnetic field control of Saturn’s polar cusp aurora

Dayside UV emissions in Saturn’s polar ionosphere have been suggested to be the first observational evidence of the kronian “cusp” (Gérard et al., 2004). The emission has two distinct states. The first is a bright arclike feature located in the pre-noon sector, and the second is a more diffuse “spot” of aurora which lies poleward of the general location of the main auroral oval, which may be re...

RF Field Analysis for High Field Magnetic Resonance Imaging Systems

The combined field integral equation method is used to calculate the RF B1 field produced by a transmission line resonator element for high field magnetic resonance systems. The proposed method provides faster electromagnetic field results than the finite difference time domain approach. A field localization method is also discussed.
