The ion temperature parallel to the magnetic field (Ti||) was varied using the ion cyclotron range of frequencies (ICRF) waves, which heat the plasma in the central cell, and by applying an additional gas puff in the central cell. Assuming the ion sound speed, \u03b3Ti|| was evaluated by a Langmuir probe, and Ti|| was evaluated in an ion energy analyzer. These parameters were combined to evaluate \u03b3. The time evolutions of \u03b3Ti|| obtained from the probe and Ti|| obtained from the energy analyzer were similar. The plasma in the end region can be regarded as collisionless, but \u03b3 was lower with ICRF heating than without the heating. A high Ti|| component was identified in the heated case. As mentioned in a previous numerical study [B. Lin et al., Phys. Plasmas 23, 083508 (2016)], it is experimentally suggested that \u03b3 can be reduced by the high Ti|| component resulting from the ICRF heating.", "subitem_description_type": "Abstract"}]},
