Here we report on a new experimental platform at OMEGA to benchmark Nernst effect in low and moderately magnetized plasma (1<Ne<10) by simultaneous direct measurement of Nernst velocity and plasma conditions. The laser produced gas jet plasma is magnetized by MIFEDS, where the Nernst velocity is measured using proton radiography [1,2] of magnetic fields at different times, while the plasma parameters (ne,Te) and radial bulk flow speed of plasma is measured by 2w optical Thompson scattering (OTS), probing different locations in plasma. The results are being compared with MHD Gorgon 1D and LILAC simulations.
