# ECRCYL: a code for electron cyclotron radiation transport

## Description

Abstract ECRCYL is a code to perform electron cyclotron radiation transport calculations in a magnetized plasma. Ray tracing is performed using the cold-plasma dispersion relation to determine ray trajectories. The plasma is assumed to lie in the annular space between two concentric cylinders which is bounded at both ends. The code takes account of plasma dispersion and collective effects due to finite density. The variation of the absorption coefficient with the angle of propagation, wave frequency a... Title of program: ECRCYL Catalogue Id: ACGT_v1_0 Nature of problem The code performs electron cyclotron radiation transport calculations in a magnetized cylindrical plasma, taking account of plasma dispersion and modification of wave absorption due to finite plasma density. High accuracy calculations can be performed. With minor modifications, the code can handle the effects of spatial variations of wall reflectivity, and 'polarization scrambling' due to reflection at the wall.
