Spheromak - Wikipedia
A spheromak is an arrangement of plasma formed into a toroidal shape similar to a smoke ring. [1] The spheromak contains large internal electric currents and their associated magnetic fields arranged so the magnetohydrodynamic forces within the spheromak are nearly balanced, resulting in long-lived ( microsecond ) confinement times without ...
The Spheromak - SpringerLink
We discuss (1) the theoretical analysis of the spheromak, (recent theoretical studies are summarized and a comparison is made with other approaches), and (2) a spheromak plasma formation scheme. One of the difficult aspects of spheromak research is to produce a toroidal plasma in the absence of coils down the axis of rotational symmetry.
One of the difficult aspects of spheromak research is to produce a ·toroidal plasma in the absence of coils down the axis of rotational symmetry. A novel plasma formation scheme has been developed at PPPL to create a toroidal plasma by using a flux generating core technique.
The Swarthmore Spheromak Experiment - Frequently Asked …
What is a spheromak? A spheromak is a toroidal ring of plasma in equilibrium according to basic MHD equations of motion; it is a good source of stable magnetofluid for reconnection experiments. The plasma contains helical currents and …
The Swarthmore Spheromak Experiment
The Swarthmore Spheromak Experiment (SSX) studies fundamental plasma physics phenomena such as magnetic reconnection using rings of plasma called spheromaks. Current experiments measure the energy and angular distribution of particles that are accelerated by magnetic reconnection of two merging spheromaks.
The Swarthmore Spheromak Experiment - The Spheromak …
1996年2月16日 · A spheromak forms when the gun field is large enough to overcome the stuffing flux. When the stuffing flux is too large, the plasma will not escape the gun and is "stuffed" in the gun. The formation threshold refers to the point beyond which increasing gun current forms spheromaks and before which the gun remains stuffed for a given stuffing flux.
The Spheromak path to fusion energy (Technical Report)
1998年4月1日 · The spheromak is a simple and robust magnetofluid configuration with several attractive reactor attributes including compact geometry, no material center post, high engineering {beta}, and sustained steady state operation through helicity injection.
Scaling studies of spheromak formation and equilibrium
1998年4月1日 · Formation and equilibrium studies have been performed on the Swarthmore Spheromak Experiment (SSX). Spheromaks are formed with a magnetized coaxial plasma gun and equilibrium is established in both small (d small =0.16 m) and large (d large =3d small =0.50 m) copper flux conservers.
Spheromak Formation by Steady Inductive Helicity Injection
2006年9月15日 · A spheromak is formed for the first time using a new steady state inductive helicity injection method. Using two inductive injectors with odd symmetry and oscillating at 5.8 kHz, a steady state spheromak with even symmetry …
Sustained Spheromak Physics Experiment (SSPX): design and …
2012年10月9日 · The Sustained Spheromak Physics Experiment (SSPX) was a 1 m diameter spheromak formed by coaxial helicity injection (CHI) and used to study spheromak physics with a focus on sustained, long-pulse operation and the possibility of achieving steady-state or quasi-steady state operation with good energy confinement.
