Title: Local one-dimensional ICRF full-wave solutions valid to all orders in k{sub (perpendicular} {sub sign)}{rho}

Abstract

High harmonic ion cyclotron resonances are important for understanding future fast wave heating experiments on NSTX1 as well as recent ICRF flow drive experiments on PBX-M2 and TFTR3. Unfortunately, many of our ICRF wave analysis codes are based on an expansion to second order in k{sub (perpendicular} {sub sign)}{rho} where k{sub (perpendicular} {sub sign)} 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 codes4,5 on the other hand, are valid to all orders is both k{sub (perpendicular} {sub sign)}{rho} and {rho}/L where L 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}/L<<1), while still retaining all orders in k{sub (perpendicular} {sub sign)}{rho}. This allows high harmonic fast wave and flow drive applications, while requiring less computing time than conventional integral codes. (c) 1999 American Institute of Physics.
