  This paper evaluates the feasibility of helicon current drive (HCD) in a
hybrid scenario for the China Fusion Engineering Test Reactor (CFETR).
Utilizing the GENRAY/CQL3D package, a large number of simulations (over 5 000)
were conducted, with parametric scans in the antenna's poloidal position,
launched parallel refractive index, and wave frequency. The analysis reveals
that helicon has excellent accessibility under reactor-level conditions, and
smaller n|| and higher wave frequency result in enhanced wave absorption. The
simulations demonstrate an optimal launched parallel refractive index of
approximately 1.6 for the CFETR hybrid scenario. The best launch position is
found to be within a poloidal angle range of 25 degrees to 65 degrees.
Additionally, it is preferable to have a narrow parallel refractive index
spectrum for wave absorption when operating below the threshold value of
{\Delta}n|| (~0.6), beyond which the effect of {\Delta}n|| on wave absorption
is negligible. This study provides valuable insights into the potential
application of HCD in CFETR.
