TGLF transport model predictions have been assessed in the vicinity of a theoretical high β burning plasma spherical tokamak at Q=10. Linear micro-stability
calculations from TGLF have been compared on a surface at mid-radius with the
gyrokinetic code GS2. Differences between TGLF and GS2 spectra can be characterised by the RMS difference in growth rates, σγ. We find considerable improvement in the quality of TGLF growth rate spectrum can be achieved by increasing
the number of parallel basis functions and by tuning the TGLF parameter used in
the model for trapped particles, θtrap.
