Secondary fast reconnecting instability in the sawtooth

We consider magnetic reconnection in thin current sheets with both resistive and electron inertia effects. By analysis of secondary instabilities we show that, when the current sheet is produced by a primary instability of the internal kink type (large ' ), reconnection proceeds on a time scale much shorter than the primary instability characteristic time.

Calcite Processing Crusher Mill,Calcite Pulverizer For

Secondary crushing, if necessary and economic, is accomplished by using standard cone crushers followed by short head cone crushers. The subsequent crushing is called fine crushing, and it can be achieved by using various kinds of grinding mills. For example, you can choose ball mill, super thin grinding mill, vertical grinding mill and so on.

Introduction to Mineral Processing or Beneficiation

3.2.1 Crushing Equipment. Primary Crushers Jaw and Gyratory. Within the crushing circuit, a primary crusher reduces material down to a size that can be conveyed and fed to the secondary crushing circuit. The two most common primary crushers used for coarse runofmine material are the jaw and gyratory crushers.

Magnetron Radartutorial

The magnetron is a highpowered vacuum tube that works as a selfexcited microwave oscillator. Crossed electron and magnetic fields are used in the magnetron to produce the highpower output required in radar equipment. These multicavity devices may be used in radar transmitters as either pulsed or CW oscillators at frequencies ranging from approximately 600 to 95,000 megahertz.

Secondary Fast Reconnecting Instability in the Sawtooth Crash

Summary and conclusions A current sheet generated by a primary instability with '= , such as the resistive internal kink mode, becomes unstable at an early stage in its nonlinear development because of sub Alfvenic modes. In the case of sawtooth phenomenon in a purely resistive framework the current sheet becomes unstable to a secondary mode with growth rate

Physics Demonstrations Magnetism

5. MAGNETISM Magnetism brings to mind horseshoe magnets and iron filings. However, magnetism is very closely related to electricity. In 1819 the Danish physicist and chemist, Hans Christian Oersted (17771851), during a lecture demonstration, observed that an electric current can affect a magnetic compass needle * and thus united what until then had been viewed as two distinct subjects[1].

Pinch (plasma physics)

A pinch is the compression of an electrically conducting filament by magnetic forces. The conductor is usually a plasma, but could also be a solid or liquid metal.Pinches were the first type of device used for controlled nuclear fusion.. The phenomenon may also be referred to as a Bennett pinch (after Willard Harrison Bennett), electromagnetic pinch, magnetic pinch, pinch effect or plasma pinch.
