Interchange modes in a collisional plasma
Gross plasma stability can derive from plasma compressibility in the bad curvature regions of closed field line systems. In this situation magnetohydrodynamic ~MHD! theory predicts that the maximum pressure gradient that is stable is proportional to g , the ratio of specific heats. This article will examine the accuracy of the MHD prediction for electrostatic interchange modes using kinetic the...
متن کاملElectronic Data Interchange: A Definition and Perspective
Introduction In most firms, a significant effort is spent communicating with other firms. The information exchange pertains to such matters as requests for quote, bids, purchase orders, order confirmations, shipping documents, invoices, and payment information. A recent survey showed that almost 80% of the documents transacted between firms use paper as the medium to carry the information. Elec...
متن کاملStabilization of interchange modes by rotating magnetic fields.
Interchange modes have been a key limiting instability for many magnetic confinement fusion configurations. In previous studies intended to deal with these ubiquitous instabilities, complex, transport enhancing, minimum-B producing coils were added to the otherwise simple linear mirror plasma. Possible solutions for returning to a simple symmetric mirror configuration, such as ponderomotive fie...
متن کاملExtended MHD Study of Interchange Modes in Spheromaks
Extended MHD effects on pressure driven interchange modes are studied in decaying spheromak equilibria. Equilibria at conditions relevant to high temperature SSPX[Hooper et al., Nucl. Fus. 1999] discharges are ideal interchange unstable. Extended MHD introduces drifts which have a stabilizing effect, reducing the linear growth rate, on the high-n modes. However, extended MHD has a mixed effect ...
