  1. HT-7 Study of LHW current drive efficiency and volume averaged electron temperature Proposal for HT-7 Experiment YOUNIS Jawad, and WPI

  2. HT-7 The current drive efficiency is one of the most important parameter in non-inductive current drive. The electron temperature dependence of CD efficiency has been suggested by comparing many experimental results in small and medium size machines [1]. Experimental Results have shown that the CD efficiency increases with electron temperature [2]. In 1989 the empirical scaling of the CD efficiency has been found in JT-60 experiments [3] Current drive efficiency ~12<Te>/5+Zeff, where <Te> is the volume averaged electron temperature and Zeff is the effective ion charge [1] M.Porkolab, IEEE Transactions on Plasma Sciences,PS-12 (1984)107 [2] V.V.

  4. HT-7 Plasma parameters, PLH = 100 KW up to maximum available ,Δ = 0 Ip= 80 kA ne= 0.7, Ip= 140 kA ne= 0.7, Ip= 140 kA ne= 1.5, Diagnostics required, Density, Te ( SXR)

  5. HT-7 We will make use Lower Hybrid Simulation Code (LSC ) to analyze our data numerically, and we try to compare the experimental results with numerical results
