Edge profiles in Ohmic and lower hybrid(LH)wave heated discharges in EASTare presented.A comparison of the measured profiles is made with those from the theoreticalprediction for the scrape-off-layer(SOL)width.The edge plasma parameters are diagnosed bya triple probe divertor diagnostic system and fast reciprocating probes at the outer mid-plane.The experimental results show that the SOL width of double-null(DN)divertor plasmas in EASTappears to exhibit a negative dependence on the power crossing the separatrix,which is consistentwith the collisional SOL scalings of JET and Alcator C-Mod.This will provide useful informationfor extrapolation to the ITER SOL width scaling for power deposition.
