Book Description
Cross and Manheimer/Lashmore-Davies sell steadily in the export market - potential for Cairns here. This book provides a concise introduction to the basic physics of radiofrequency heating. Most existing literature on the subject is at the research level, aimed at specialists in the field. It provides a survey of theoretical and experimental results with a large number of references to help the reader wishing for more detail. Provides a concise and readable account/ Basic physical principles are emphasised and more complicated mathematical ideas are explained in outline. Radiofrequency current drive is discussed in detail. "One criticsm may be lack of detail. I have deliberatly avoided including a lot of mathematical and experimental detail in order to keep the book short and to concentrate on the essential ideas. Enough references are given to lead anyone wishing more detail to the appropriate literature" - comment from the author? Export Market: Japan, USA, CERN, all important centres for fusion research Tokamaks - supercolliders for particle acceleration - particles are bombarded by extremely powerful lasers the beams of which are split many times through kms of piping - massive structurees largest currently in Japan but also important structure in US.

Book Description
Ultra-small aspect ratio tokamaks present a totally new plasma environment for heating and current drive experiments and involve a number of physics issues that have not previously been explored. These devices operate at low magnetic field and relatively high density so that the effective dielectric constant of the plasma to high harmonic fast waves (HHFW), is quite high, and perpendicular wavelength of fast waves is very short.[lambda][approximately] 2.0 cm compared with[lambda] - 10-20 cm. This makes possible strong electron absorption at high harmonics of the ion cyclotron frequency, [Omega][sub i], and at fairly high phase velocity in relation to electron thermal velocity. If the antenna system can control the parallel wave spectrum, this offers the promise of high efficiency off-axis current drive and the possibility for current drive radial profile control. Antenna phasing is ineffective for profile control in conventional tokamaks because of central absorption. There are also challenges for antenna design in this regime because of the high dielectric constant and the large angle of the magnetic field with respect to the equatorial plane ([approximately]45[degrees]), which varies greatly during current ramp. Preliminary experiments in this HHFW regime are being carried out in CDX-U.
