The plasma potential up to 100 V was found in the region that does not map along the magnetic field line to active I-port antenna. This enhancement correlates with the local fast wave intensity. An increase in the loading resistance and heating efficiency was observed at a low parallel wave number. The higher heating efficiency is seen to cause lower unabsorbed fast wave power in the SOL regions. This can cause a decrease in the fast wave field intensity that reaches plasma facing components and can result in a decrease in the plasma potential and slow wave intensity. <a href="http://library.psfc.mit.edu/catalog/reports/2010/19ja/19ja058/abstract.php">PSFC REPORT PSFC/JA-19-58</a><br /><br />This work was supported by DoE grant 6928419.
