【 摘 要 】

More than 90 years passed when name plasma was coined and more than 60 years in controlling plasma. It seems to be missing something, may be entropy that depends upon maximum constituents of plasma. Inculcating entropy in theoretical and experimental research may lead to the easy confinement. In this paper, Yaqub's work is extended, transport phenomenon is studied with drift approximation inculcating entropy and η-mode depending upon entropy gradient drift is observed. New dispersion relation is derived by using Branginskii transport equations. Dependence of Anomalous transport on entropy is also observed. This work will be helpful in understanding different phenomena of space plasmas and tokamak specifically the pedestal H-mode.
