survey of modes and their effects in ORMAK, ISX-A, and ISX-B

PDF Version Also Available for Download.

Description

A comparison of some features of the three tokamaks is given. The ORMAK and ISX-A have ceased operation. The ISX-B has completed a checkout phase with studies of circular, ohmically heated plasmas in which it performed much like ISX-A. Shaped and injection heated plasmas are being studied. Diagnostics for mode structures were the usual Mirnov loops for approx.B/sub theta/ and collimated soft x-ray detectors for the internal fluctuations approx.X. The approx.X measurements on ISX-A, and thus far on ISX-B, used only a single x-ray channel which veiwed vertically across the center of a minor cross section. Multiple channels were used ... continued below

The approx.X measurements on ISX-A, and thus far on ISX-B, used only a single x-ray channel which veiwed vertically across the center of a minor cross section. Multiple channels were used on ORMAK in a fashion which permitted m number determinations at several plasma radii. For detailed studies, analog signals were stored on magnetic tape and later digitized for fast Fourier transform analysis.
