Local One-Dimensional ICRF Full-Wave Solutions Valid to All Orders in k-Perpendicular-Rho

PDF Version Also Available for Download.

Description

High harmonic ion cyclotron resonances are important for understanding future fast wave heating experiments on NSTX 1 as well as recent ICRF flow drive experiments on PBX-M<sup>2</sup> and TFTR<sup>3</sup>. Unfortunately, many of our ICRF wave analysis codes are based on an expansion to second order in k-perpendicular-Rho where k-perpendicular is the perpendicular wave number, and Rho is the Larmor radius. Such codes are limited to cyclotron harmonics less than or equal to 2. Integral codes<sup>4,5</sup> on the other hand, are valid to all orders in both k-perpendicular-Rho and Rho/<i>L</i>L where <i>L</i> is the equilibrium scale length. But velocity space integrals ... continued below

Description

High harmonic ion cyclotron resonances are important for understanding future fast wave heating experiments on NSTX 1 as well as recent ICRF flow drive experiments on PBX-M<sup>2</sup> and TFTR<sup>3</sup>. Unfortunately, many of our ICRF wave analysis codes are based on an expansion to second order in k-perpendicular-Rho where k-perpendicular is the perpendicular wave number, and Rho is the Larmor radius. Such codes are limited to cyclotron harmonics less than or equal to 2. Integral codes<sup>4,5</sup> on the other hand, are valid to all orders in both k-perpendicular-Rho and Rho/<i>L</i>L where <i>L</i> is the equilibrium scale length. But velocity space integrals in these codes require long running times. Here we take a simpler approach which assumes a local plasma conductivity (Rho/<i>L</i> << 1), while still retaining all orders in k-perpendicular-Rho. This allows high harmonic fast wave and flow drive applications, while requiring less computing time than conventional integral codes.
