Non-thermal acceleration of particles in the solar corona is evident from both remote hard X-ray (HXR) and in-situ observations of high-energy emission, however the plasma and turbulent properties of the source acceleration region(s) are not fully understood. Correlation of spectral indices from these two populations suggests the existence of a common source region in the corona. To better constrain the properties of this source region, we perform a parameter study of the collisional plasma and turbulent acceleration properties and how these properties individually affect in-situ electron spectra at distances out to 1 AU. In addition, we investigate how significant the effects of coronal non-thermal scattering are on in-situ spectra. We then perform a test-case of dual simulated datasets for HXR and in-situ spectra initialised within a shared source region with equivalent turbulent acceleration properties. By comparing their spectral properties, we discuss the feasibility of reproducing the correlation of spectral indices.
