The Numerical Calculation and Analysis of　the　Spectrum　of　LH　Waves　Launched by Grill-Type Antenna on HL-2A Tokamak

摘要

The LHCD antenna that will be used in HL-2A is the original one used in HL-1M,which will be modified. We measured the feature of the antenna. The features include the reflection of main waveguide, VSWR, the adjacent phrasing between the sub-waveguides and so on. The paper describes the measured results and spectrum calculation based on the measured parameters. From the works we can appreciate our antenna correctly which will be useful for LHCD experiment on HL-2Ain the year.
