Already in the early 19th century, G. Lamb brought to notice the possibility of representing a velocity field in the form of the superposition of potential and purely solenoidal fields. In the work by Sretensky, this viewpoint is sequentially carried out, the efficiency of such a representation is shown, and its justification is given.”The idea is to reach the steady state field value in the gun faster than the time constant of the gun would allow when using a flat incident rf pulse. By increasing the incident power by about a factor of three and then decreasing the incident power when the field reaches the desired value in the gun, the field build up time can be decreased by ...solenoidal magnetic field [10]. The cooling section (CS) of a typical cooler, a straight section of the storage ring where electrons copropagate with ions at the same average velocity, is immersed in a continuous solenoidal field matching [11] the field at the cathode. After each passage the electrons are either dumped or returned to the gun forThe solenoidal field within the detector causes coupling between beam oscillations in the horizontal and vertical directions. Therefore, compensation solenoids are required to keep the circulating particle more » beams from seeing the effects of the field from the main detector solenoid.For the strong magnetic field, the longitudinal separation and transverse focusing of the long bunches disappear. We attribute these phenomena to the reason that the strong solenoidal magnetic field restricts the transverse movement of plasma electrons.

There are three toroid magnets in ATLAS: two at the ends of the experiment, and one massive toroid surrounding the centre of the experiment.. At 25.3 m in length, the central toroid is the largest toroidal magnet ever constructed.Calculation of electric field via the scalar electric potential \(\Phi (\varvec{r})\) is a standard approach in in electrostatics. However, the steady electric field in charge-free regions simplifies both to being an irrotational \(\nabla \times \varvec{E} = 0\) and divergence-free \(\nabla \cdot \varvec{E} = 0\) field. Hence, an electric vector potential can be associated with this field, in ...A charged particle in a magnetic field travels a curved route because the magnetic force is perpendicular to the direction of motion.

Show ...But a solenoidal field, besides having a zero divergence, also has the additional connotation of having non-zero curl (i.e., rotational component). Otherwise, if an incompressible flow also has a curl of zero, so that it is also irrotational, then the velocity field is actually Laplacian.That the field lines circulate in tubes without originating or disappearing in certain regions is the hallmark of the solenoidal field. It is important to distinguish between fields "in the large" (in terms of the integral laws written for volumes, surfaces, and contours of finite size) and "in the small" (in terms of differential laws). This is similar to Poisson's equation but it is terms of a vector potential. e.g. magnetic field within a conductor carrying a steady current, Rotational motion of an incompressible fluid, time varying electromagnetic field in charge free and current free region.
